# 1.01 Incremental Support

In all cases, the highest US CMS priority is to retain the support
granted to our groups in prior fiscal years. That support was largely
for postdoctoral research candidates with appointments lasting several
years or for professional help, e.g. engineers. In order to avoid "end
effects" caused by coming up the "learning curve" a sustained support of
more than one year is required in order to maximize the return on the
initial investment made by the funding agencies.

The material presented below is a request increment to that support.
While it is recognized that funds are limited, the US CMS detector
construction project will continue to ramp up in FY02. As the project
progresses, the need for postdocs will become more acute, since critical
thought is needed to evaluate, calibrate and test the devices
constructed by the engineers and technicians. Thus, as the life cycle of
the detector moves ahead, the needs of the project will lean ever more
heavily on physicists, whose support is outside the purview of the
construction project. To insure the success of the project, this support
must be found. It is imagined that a high level of support will carry
over into the research phase of US CMS.

**1.02 Impact of Prior Incremental Postdoc and Engineer Support on US
CMS:**

HCAL and Jet/Missing ET Group -- U. Maryland:

Maryland current has one postdoc, Salavat Abdullin, working full

time on CMS. Salavat has been essential to the progress of the

HCAL/Jet/Met group, and has also the understanding of the algorithms

that are used to do time sample-to-energy extraction.

His work in the HCAL/Jet/Met group includes:

1\) He updated the ntuple maker and produced the ntuples that the

jet/met group has used from spring 2000 until now (finally, this week,
we have

new ntuples)

2\) did a study on how to improve the L1 MET trigger using jet energy

corrections (published in CMS note IN-2000/060)

3\) study using CMSJET showing the relative sizes of various
contributions

to the MET resolution (published in CMS note 2001/005)

4\) rate calcuations and turn-on curves for jets after energy
corrections

(published in CMS note IN-2001/001)

5\) studies on case for SUSY at 10\^35a

6\) maintenance of CMSJET, the fast simulator for CMS

His work on algorithms for time-to-energy extraction for the HCAL
includes:

1\) placing a proper simulation of the HCAL electronics into ORCA

(a very hard job!)

2\) writing a toy Monte Carlo to study various options for time sample

to energy conversion for both the level 1 path and the DAQ path

(in parallel and extending the work of Dan)

A note exists on this work, and will be released by the end of next

week (I just need to read it one more time, and its the first week

of classes here at MD)

In the future, Salavat will do work in the following areas:

1\) checking the effect of the various time sample to energy algoritms

on Zprime mass resolution in the full ORCA environment

2\) designing and writing code within the ORCA framework to do

testbeam analysis

3\) designing trigger tables for SUSY -\> jets+MET

4\) designing algorithms that use tracking in the level 3 trigger to

move jets from pileup events from the multijet triggers.

The management of interational CMS has recently tried to draw attention

to the importance of the PRS work by reorganizing its management. The

jet/met group was renamed, the scope of its charge was enlarged, and it
was

made a fully integrated project task of HCAL on CMS.

The new charge to the HCAL/jet/met group is:

1\) develop simulation tools (GEANT3, GEANT4, and fast mc)

2\) C++-based code (ORCA) for the reconstruction of HCAL

3\) develop software and offline analysis strategy for calibrating

the HCAL, jets, and MET

4\) design higher-level trigger (HLT) and offline algorithms for jets
and MET

5\) develop trigger tables for physics channels involving jets and MET.

6\) develop physics strategies for analyses containing jets/met.

Our milestones are:

1\) finish developing HLT algorithms for jets and MET by the end of

2001\.

2\) finish designing low and high luminosity trigger tables by end

of 2002

3\) have GEANT4 fully developed by end 2002

4\) produce physics TDR by mid 2004

Our currently active (=people who have presented work they have done

(not just plans for work) in a HCAL/jet/met meeting by today\'s

date 9-Jul-01) are:

myself(MD): group management

Shuichi Kunori(MD): group management

8\) maintaining web page for jet/met data samples

HCAL -- Notre Dame

Dan Karmgard is critical for our Notre Dame contributions to CMS, for

several reasons.

First, almost all ND physics personnel are working on Dzero some major

fraction of time. Only Dan and I are devoted in full force to CMS. So

for our contribution to the experiment, it is really key for me that Dan

is working nearly full time on the effort. He does do some consulting

on Dzero analysis and teaches a course on statistical methods (one night

a week) at ND to help develop teaching skills.

Second, on CMS HCAL he is involved in very significant ways in:

QC system development for ODU manufacture

Magnetic field issues for HO RBX

Thermal testing for HB, HE and HO RBX

Participation in summer beam tests of HCAL wedges

These items have been significant over the last year and will continue

to be significant for at least the next year as well, particularly with

ongoing ODU production here at Notre Dame and as we head into the next

round of beam testing in H2 at CERN next summer.

Thus it is extremely important for me that we keep his position here in

our ND base program.

Forward Pixel Group

Our US-CMS Pixel group is now moving into its final preparation for the
assembly of the forward pixels for US-CMS. Most of the manpower on this
project (students, RA's, and senior physicists) is supported by the base
program: DOE or NSF. This support is indispensable and it is immensely
appreciated.

For example, Dr. Lalith Perera at Rutgers, has been working on the
design of the communication Hub (CNH). More recently Steven Worm has
shown his expertise (from his previous work with CDF) by studying the
design of the Very High Density Interconnect (VHDI). This is probably
one of the most challenging components of the project. Gino Bolla
(engineer at Purdue), with help from graduate student Kim Giolo, has
recently completed our new submission for pixel sensors. Amitave Roy
(also a graduate student at Purdue), working with Gino Bolla, has
characterized sensors from our first submission after they were
irradiated at UCD or at Indiana University. The results of these
measurements were essential in selecting the design of the structures
included in the latest submission. Both RA's associated with
Northwestern University are in residence at SiDet. Sudhir Malik has,
among many tasks, continued to work on the read-out of chips with or
without sensors. Signals were observed from radioactive sources after
triggering the read-out electronics with signals from scintillators.
This job has been made particularly difficult by noisy chips made by
DMill. Considerable progress was accomplished in enhancing the signal to
noise ratio. Mikhail Kubantsev has concentrated on assembling models of
"Butterflies" (units of pixel detectors). This work allows him to
identify the most efficient assembly method. It tests the functionality
of the equipment, trains operators, and allows us to determine the
accuracy achievable in producing the pixel detectors for US-CMS. More
recently, Mikhail has repeated the survey of three models of Butterflys
as a function of temperature between +20°C and --20°C.

As clearly demonstrated by this long list of accomplishments achieved by
physicists who are all supported by the base program, DOE and NSF
support plays a vital role in the US-CMS pixel project. We are very
grateful for this generous support.

ECAL Group:

The Minnesota postdoc, Ivan Kronkvist, for whom funding has been phased
in over the past two years 1/3; 2/3 and in the coming year full-time,
made a magnificent effort to build the Califormium source (he really was
a sine qua non). He learnt a nuclear reactor design code to compute the
radiation levels and the materials required, he took care of the
day-to-day issues during construction and played a major part in the
source transfer. He is now working on the design and operation of the
APD database for tracking the 130,000 APD's we are receiving.

1.  **EMU:**

1\. Senior research physicist at CERN, UF, \$80K

EMU group urgently needs a senior physicist based at CERN to lead

the installation and commissioning effort. The installation and

commissioning of the Muon system starts next year, the preparation need
to

start immediately.

For the first year \$40K would be sufficient,, and for the second year

\$60K are needed, UF will supplement it in the first two years using

matching funds

2\. Detector Controls System physicist at CERN, Purdue \$40K. DCS effort
in

EMU needs a full time physicist (posdoc). Purdue is interested in

contributing to this effort, they will contribute \~50% from their
existing

base program

3\. Research physicist at CERN, UCLA (Cline), \$40K. UCLA will
contribute

\~50% for the salary from their existing base program. This physicist
will

be one of the leaders in the installation and commissioning effort

4\. Supplement for the salary of R.Breedon, UCDavis, \$40K.

Richard Breedon is the Associate Technical Coordinator of the EMU group.

Currently he has to teach part time to have enough support. It would be

beneficial to have him full time doing research.

**1.2** **HCAL:**

## 

Personnel request (priority ordered)

1\. Boston: Post Doc for CMS electronics

2\. Maryland: Post doc to work on PRS

3\. Purdue: Post doc to work on sourcing

4\. FSU: Post doc to work on calibration and DCS at CERN

5\. Iowa/Iowa State/Fairfield: 3/4 Post-doc to work on Phototubes

and HF at CERN

Justifications (alphabetically by Institute):

Boston University

=================

Boston University is playing a major role in the design and construction

of the HCAL electronics. We are responsible for the data concentrator

cards(DCC) which serve all of HCAL as well as the front-end electronics

for the forward calorimeter (HF). The prototype version of these

electronics must be delivered for use in the 2002 test beam at CERN. The

cost of these items for which Boston University is responsible (WBS

2.1.7 for the DCC and WBS 2.5.5 for HF) is approximately \$1M.

We have three major tasks ahead of us during the coming year in which

physicists must play the primary role:

source calibration

integration of the HTR and DCC modules

CERN 2002 test beam

All three of the above activities involve an enormous amount of

hardware,

software, and firmware. As we look forward to the manufacture of the

electronics modules and their testing installation at CERN in 2004, HCAL

is facing a huge potential manpower shortage. Indeed this was the

biggest hurdle faced by both the D0 and CDF experiments at their

respective stages of construction as cited by Dan Green during the

Lehman review.

At this time we ask for support for a new postdoctoral fellow

to help guide this task to completion.

FIT (Florida Institute of Technology) Request

=============================================

FIT does not have a DOE/NSF Grant

Dear Colleagues:

This note is to request assistance with obtaining base funding to hire a

post-doc to work on CMS. As you know, although not formally, the Florida

Tech High Energy Physics group has now joined the CMS Collaboration \^Ö

the formal admission will be in September 2001; I expect no difficulty.
I

am in the process of completing the MOU with USCMS/Fermilab, which I
will

soon mail out. We are also preparing a proposal to DOE to obtain base

funding for our group.

In my most recent discussions with HCAL and HF management, it was agreed

that Florida Tech would take on the HF calibration and monitoring task,

particularly the LASER and LED calibration. I am certain that our group

can make a significant contribution to the overall design and

construction as well as detailed hardware and software needs of this

important task.

Presently, there are two faculty (Marc Baarmand and Laszlo Baksay),
three

graduate and two undergraduate students actively involved with the CMS

project. We have been searching for a new faculty to join the Physics

Department and our CMS effort, a short list has been made and we hope to

have her/him on board this fall.

We are also searching for a postdoctoral research associate to start to

work on our CMS effort as soon as possible. Here are some of the

near-term tasks for a post-doc:

\- help design and implement a LASER and LED calibration scheme for HF,

\- set up the lab and other infrastructure needed for this research
work,

\- write software and prepare a calibration database,

\- participate in HF test beam activities at CERN and other tests at

Fermilab,

\- conduct Monte Carlo studies for HF calibration based on physics

processes,

\- help with Monte Carlo studies for HF physics benchmark processes.

The Florida Tech HEP members have years of experience in the field but

our HEP program is still in its infancy. It is clear that our group
needs

a full-time scientist to improve productivity and visibility in CMS.

Addition of a post-doc to our group will bring about the critical mass

necessary to make a significant contribution to the HF project and to

help make our participation in CMS a success.

FSU (Florida State University) Requests (2)

============================================

Calibration Post Doc at CERN (FSU)

\$70,000

The assembly and QA testing of the megatiles at CERN have demonstrated

that we need more manpower at CERN. I am not sure that the present

manpower can accomplish this task as well as the calibration in the test

beam and at UX5 with the existing personnel. In addition we need a
person

at CERN who can keep the databases and then reformat for PVSS II. This

position will be based in CERN.

Here is a list of many of the components of the HF. The intention of

this list is to give an overview of the work that is related to HF in

order to evaluate what tasks Ianos Schmidt and the IOWA/ISU/FAIRFIELD
can

do in order to guarantee a successful completion of the project.

READOUT BOXES

\* PPP I was designed and built by Ianos at the University of IOWA.

\* PPP II design needs to be completed and a prototype built.

Remaining issues that need to be resolved to complete this task:

\* Specifying the PMT base electronics/readout box interfaces
(electrical

and mechanical).

\* Specifying electrical and service connectors and related hardware

interfaces.

\* Verify that magnetic shielding requirements are adequate.

\* Complete specification of the readout box / back plane interface.

We have discussed the PMT base electronics interface with Claudio
Rivetta

in order to keep the readout box design and base electronics packaging

design efforts synchronized. Most of the issues relating to the readout

box, back plane, and light guide interfaces have been resolved with

collaborative effort between Vladimir Sidorov and Ianos Schmidt What

remains is the specification of the mounting and support hardware.

The magnetic shielding consisting of mu-metal and carbon steel tubing

has never been tested to determine if it is sufficient. At the moment it

looks like the magnetic fields from the vacuum pump behind HF might

be more of a problem than those from the CMS magnet. It may be

useful to prototype a subsection of the readout box consisting of

a single PMT assembly. This prototype could then be used to test the

effectiveness of the magnetic shielding and evaluate the integration

of the base electronics packing into the readout box design.

LIGHT GUIDES

\* The light guide prototype for \"PPP I\" was designed and built at
Iowa.

\* Light guides were integrated into the design of the backplane
components

and ferrules through discussions with Vladimir Sidorov.

\* Some radiation damage studies were performed at IOWA on the HEM

reflector material.

Remaining issues:

\* Light guide assembly procedures must be determined.

\* Appropriate materials for construction must be determined.

\* Production schedule and QC must be established.

SOURCE DRIVER SYSTEM

\* Prototypes of the source tubing couplers were designed at IOWA.

\* Source tubing pathways were modeled and evaluated at IOWA.

\* source tubing pathways and couplers were integrated into the

wedge backplane and strong back design with collaboration with Vladimir

Sidorov.

Remaining issues:

\* Source driver locations must be determined and mechanical drawings of

the source drivers must be provided to Churin\'s team to be

incorporated into the HF design.

\* Plastic source tubing pathways and bundling scheme must be
established.

\* Determine what is required for plastic source tubing to meet CERN
safety

requirements.

\* Construct a mock up of the worst case source tubing path to test with
a

source driver to determine if design is acceptable.

\* A prototype of the source tubing coupler must be tested and the
design

finalized.

It is our understanding that the preferred tubing is made from an

acetal based plastic which is generally considered to be an unacceptable

material in the CERN IS-41. Virgil has suggested using metal conduit to

meet the fire safety requirements and to provide protection for the

tubing. We are not sure if it has yet been determined if the material

will maintain its properties in the radiation environment of the HF over

the life time of the experiment.

We have recently communicated with Virgil Barnes about mounting and

maintenance requirements of the source drivers. There are two primary

problems that need to be solved. One is providing reasonably large bend

radii for the tubing/conduit without compromising the integrity of the

shielding. The other is determining a location for the driver that does

not interfere with other equipment and cabling while still providing

adequate access for maintenance. There has been some discussion about

ways to quickly dismount the driver so that maintenance would not have

to happen in situ.

An incomplete prototype of the source tubing coupler, designed at

IOWA, was fabricated at TTU and delivered to CERN but has not been
tested.

The design was simplified to expedite fabrication of a prototype for

evaluation and will most likely require some changes before the design
can

be finalized.

CABLES AND SERVICES

\* Initial conceptual design of service routing and evaluation of

service mechanical requirements was performed at IOWA.

Remaining issues:

\* Cable types for all HF services must be specified. This includes PMT

signals, power supply, slow controls/monitors, calibration system

(LED, PIN diodes, laser),and Nitrogen.

\* Nitrogen flow rates must be determined and nitrogen delivery system

needs to be designed.

\* Cable harness needs to be designed.

\* Tooling for harness fabrication needs to be designed, built and

tested.

\* Harness production must be included in production schedule.

The Shielding of HF is being designed such that complete cabling

harnesses can be constructed and tested prior to HF assembly. It would

be useful to construct a mock up of the cabling environment to evaluate

the harness design and contribute to the design of tooling and fixtures

for harness fabrication.

FIBER INSERTION/OPTICAL ASSEMBLY

\* A full scale wedge mock up was constructed at IOWA to study the
problem

of fiber insertion.

\* A realistic scenario for fiber processing and assembly was generated.

Remaining issues (U.S.)

\* A fiber/source tube support structure that is compatible with

the optical assembly process need to be designed.

\* Completion of design of fiber area enclosures and wedge end covers.

attachment points must be included in the wedge mechanical
specifications.

\* Evaluation and procurement of fiber cleaving technology.

\* Establishment of fiber cleave acceptance criteria and testing
methods.

\* Identify appropriate glue for potting of fibers into ferrules and/or
for

fixation of fibers to absorber.

Remaining issues (Hungarian ?):

\* Fiber marking and processing procedures.

\* Ferrule gluing procedures and QC.

\* Determine if fiber bundle strain relief is needed and how it is to be

implemented.

\* Refine ferrule design to be compatible with fiber insertion and
gluing

process.

\* Determine procedures and equipment requirements for acceptance
testing.

\* Define and test entire optical assembly process including fiber

processing, insertion, gluing, strain relief, quality checks, source

tubing installation, backplane assembly, enclosure installation, and

transportation.

Information from our efforts to understand the optical assembly

problem was provided to the Hungarian team. At CERN (March 01) Ianos

Schmidt has worked with the Hungarian team to facilitate understanding
of

the problems related to the optical assembly process. At that time he
has

also met with CERN fiber optic specialists and performed some cleaving

tests using cleaving equipment borrowed from them. Cleaving samples

of both QQ and QP fiber were sent to TTU for evaluation.

Ianos has evaluated the impact of replacing tail catcher fibers with

medium length \"hadronic\" fibers on the PMT count, bundle sizes, and
fiber

usage estimates. The current design can accommodate these changes with

little modification. Some optimization could be performed if this

decision is made before production of readout boxes and backplane

components is started.

HF CALIBRATION SYSTEM (LED/LASER)

\* A crude prototype of a readout box calibration unit was produced for
the

PPP I readout box consisting of two LED\'s two PIN diodes and a fiber

connector for injection of laser light at IOWA.

Remaining issues:

\* HF calibration system design and specification must be completed.

\* Readout box CAL units must be designed and prototyped.

\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\--

Total request is :

A\) 51 K with 20 K matching by our group ( IOWA/ISU/Fairfield).

B\) 42K with 42 K matching by IOWA.

\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\--

Iowa State Request (Hauptman)

=============================

I request support of a 1/2-time engineer to work at

Fermilab next year to support various work on HF,

including work on DCS.

Work on HF next year will require vertical integration

of the readout from a fast light pulse to the output of

the QIE, layout of power supplies, cables, etc. for RBX,

and testing of one RBX.

This engineer will be visiting ISU at Fermilab,

starting Nov-Dec \'01, for a year. This is a good match

for time and effort, and is an opportunity for ISU to

contribute engineering without having an engineering staff.

The engineer is Vladimir Atramentov from the National

Scientific Center, Physics and Technical Institute, Kharkov

(which is a CMS collaborating institution). Atramentov is

mostly a mechanical engineer, but also partly an electrical

and a production/QA engineer.

University of Maryland Request (Sarah Eno)

==========================================

I would like to request that the HCAL project management consider
including

on their annual list of requests for personel funding at Unversities

with high priority a postdoc position at the University of Maryland to

work on PRS studies.

We can not possibly cover all the PRS tasks with the existing manpower
and

make our milestones. Also, the US contribution to the project so far has
been

small (sometimes I think the jet/met group should be called the ITEP and

ITEP-in-exile group). The Maryland group was making strong
contributions.

but, then, when OPAL shut down, we lost 1/2 of our workforce

(Salavat+Silvia -\> Salavat). Silvia did all the work on the methodology

that Andrei uses to get the jet energy scale using MC information. We

will have a visitor next year from Turkey, but he will return to Turkey

after only 1 year.

If we had a new postdoc, I would assign him to coordinating the various

calibration efforts, and working on a document that we define the

interface between the hardware and software work on calibration.

Also, working on making sure we can trigger on supersymmetry. Also,

where ever in our vast list of tasks we seem to need manpower.

We need \$85K as the fully-loaded cost for a postdoc.

Purdue University

=================

Purdue University requests a post-doc to work on sourcing at CERN as
well

as source data analysis. The Purdue post-doc would also assist with

transfering the source driver stand alone code to DCS.

University of Rochester Request (Arie Bodek)

============================================

I am writing to request \$68.3K in base funds to support Dan Ruggiero

to be stationed at CERN to work on the CMS HCAL at CERN.

Pawel de Barbaro is now planning to spend about 50% of his time at CERN.

Dan Ruggiero, a laboratory engineer/technician has been working on

CMS HCAL for the past few years and has been supported by project funds.

He has worked on all facets of HCAL. Ruggiero was a physics graduate
student

at Rochester, who decided to switch into the technical area. He has

been a technician/Laboratory engineer for the past 10 years. He is a

generalist who works on hardware as well as software and computers.

During this summer, Ruggiero has been spending a considerable amount of
time

helping Pawel de Barbaro with the HCAL installation. Ruggiero would like

to live at CERN and continue to work on the commissioning, installation,

checkout and maintanance of HCAL.

ILLINOIS-CHICAGO (UIC)

=====================

Fast Electronics Post Doctoral Fellow \$70,000.

The UIC group requests funding for one postdoc to coordinate electronics
work on the US CMS HCAL Trigger and DAQ project: the Hadron Readout Card
(HRC). The postdoc would be expected to participate in D0 as well, in
order to pursue physics topics with the run II data set. We also intend
to request funding for half a postdoc salary in FY 2003 when UIC startup
funds currently supporting the CMS Silicon-tracker postdoc will be
exhausted.

The group has responsibilities for optical fibers and trigger modules in
CMS HCAL, as well as responsibility for evaluation of CMS silicon
tracker modules. The fiber project is mature, in its production stage,
and is supervised by a recent UIC graduate supported by CMS project
funds. HB optical cables will be completed within nine months. The HRC
project is in the initial prototype phase; a CMS-funded engineer is
designing a VME board to fan out the accelerator clock within HCAL
trigger crates. At least two years of development will be required
before the final 25-crate system is installed. CMS-wide changes proposed

our software contribution to this project is severely limited due to the
lack of a postdoc. The Silicon Tracker project has just begun. UIC

**1.3.1 TRIGGER:**

# 1.3.1.1: Trigger Base Program Enhancement Priorities

In response to the call for prioritization of Base Program requests for
the US CMS Trigger Project, the following requests below have been
ordered in priority. Until recently, the highest priority for the
Trigger Project is the retention of Paul Padley in his leadership role
at Rice for the Muon Port Card and overall integration of the EMU
trigger. This has been achieved with the faculty appointment of Paul
Padley at Rice University. However, this increases the urgent need a
postdoc working with Dr. P. Padley at Rice. The US CMS Project plan
actually calls for typically 1.5 postdocs working on EMU and trigger
together. Therefore, the first priority is support of a postdoc at Rice.

The second priority is support of a postdoc at Wisconsin. Sridhara Dasu
was a scientist in the group recently and was responsible for CMS
calorimeter trigger simulation and conceptual design. He has now taken
up a Wisconsin faculty position and Wisconsin group needs to add with a
post-doc to fulfill CMS obligations, particularly to continue the
physics simulations for validating the calorimeter trigger design and
complete design of tau and jet trigger hardware. The trigger studies and
in fact, the entire CMS simulation effort has been enhanced by the
utilization of the Wisconsin developed CONDOR 1000-node distributed
computing facility. The postdoc is also needed to work on the interface
to this system so that we can continue to use it.

The above two top priorities were recognized by the most recent DOE/NSF
Review of the US CMS project in May, 2001, which states in the comments
of its report: "The Wisconsin Group is presently supporting a CMS
post-doc with start-up funds that will run out in the spring of 2002.
Losing this post-doc would be a setback to the calorimeter trigger
effort. A member of the Rice group has recently moved from a base
program supported research faculty position to a tenure-track university
supported position. It is hoped that the level of base support to Rice
University will be maintained, allowing a post-doc to be added to their
CMS effort." The Trigger and Data Acquisition chapter of this report
also states as its first recommendation, "The Rice and Wisconsin groups
should each pursue funds to maintain the level of their post-doc
involvement on the CMS trigger effort."

The third priority is support for a graduate student, B. Scurlock, to
work with Darin Acosta at Florida. This student is critical for
conducting the ongoing and planned future tests of trigger hardware, as
well as contributing to the simulation effort needed to validate the
trigger algorithms and to guide the development of future algorithms as
the technology and engineering evolves.

The fourth priority is to retain the postdoc, Dr. von der Mey, working
with Professors Cousins and Hauser at UCLA. Dr. von der Mey works full
time on the development of software and firmware associated with the CSC
trigger electronics. He works on trigger primitive simulation,
simulation of electronics \"firmware\", and readout for bench testing.
He will also work on cosmic ray testing after installation. The purpose
of listing this zero cost item is to ask that the DoE support for this
postdoc continue.

The fifth priority is to provide for a technician to be shared with the
EMU and Common Projects at U. Wisconsin. A full-time technician working
in the U.W. Physics Dept. will greatly enhance the productivity of the
existing personnel and significantly reduce the cost over the hourly
technician rate at the Physical Sciences Lab. The detailed
responsibilities and activities of the technician are detailed in the
documentation below.

The sixth priority is to provide for a supplement to move the lead
Wisconsin Engineer on the trigger onto the Base Program. The partial
support by project funds is problematic in that the engineering budget
for the trigger is tight and additional unbudgeted items caused by CMS
integration have strained it further. This engineer will also be needed
in the operations phase of the project and movement to support on the
base program will solve this difficulty at the end of the project.

The seventh priority is to increase support for travel and general
infrastructure for all of the trigger institutes.

These priorities are summarized in the following table.

  -------------- --------------------------------------------- ----------------
  **Priority**   **Item**                                      **Cost (K\$)**

## CMS Base Program Enhancement at U. Florida

*Prepared by D. Acosta*

The US-CMS Trigger group at the University of Florida is responsible for
the design, simulation, and construction of the Level-1 CSC Track-Finder
trigger for the CMS Endcap Muon system. The Sector Processors that
compose this Track-Finder must identify muons from trigger primitives in
the cathode strip chambers of the Endcap Muon system, measure the
transverse momentum in the non-uniform magnetic field and high rate
environment, and report the number and quality of muons to the Level-1
Global Trigger. The first prototype of this processor was constructed
and successfully tested in FY00.

**Scientific Staff:**

Assistant Professor D. Acosta leads the EMU Trigger Track-Finder
project; Assistant Scientist S.M. Wang and graduate student B. Scurlock
assist with the trigger simulation and validation of the design; and UF
engineer A. Madorsky as well as engineers V. Golovtsov and L. Uvarov
from the St. Petersburg Nuclear Physics Institute assist with the
hardware design, construction, and test. The CSC Track-Finder under
development at UF is composed of 12 Sector Processors (with Sector
Receiver logic merged on-board), a custom GTLP backplane, and a DAQ
connection to an Endcap Muon Detector-Dependent Unit.

In the last year, D. Acosta and S.M. Wang were successful in
implementing a C++ model of the first-generation Sector Processor
prototype into the ORCA simulation framework of CMS. This model was used
for the efficiency and rate estimates published in the CMS Level-1
Trigger Technical Design Report, and the Endcap Muon trigger was shown
to be viable at full LHC luminosity, although with only a small safety
margin. Current work now includes incorporating changes in the Sector
Processor design to reduce the latency of the processor as well as
improve the selection algorithms and Pt assignment to further reduce the
trigger rate. A second prototype will be constructed and tested in Fall
2002.

Support for one graduate student (B. Scurlock), including salary,
tuition, and associated travel to trigger meetings, is requested at
\$35K. This student plays a critical role as a liaison between the
UF-based design engineer (A.Madorsky) and the CMS Muon Physics
simulation group. In particular, the student is expected to implement
the design improvements in the Sector Processor logic into the ORCA
simulation environment to validate the Level-1 trigger and the overall
physics selection capability of CMS. This work requires daily
interaction with the engineer to provide feedback on the Verilog to C++
translation and on the tuning of the trigger logic needed to achieve the
best efficiency and rate reduction. With a staged CMS detector now under
consideration by the Collaboration, it is imperative to have the best
CSC trigger possible in time for LHC turn-on. The student also will
assist with system tests of the new Track-Finder electronics starting
Fall 2002.

**Technical Staff**

The technical staff associated with this project presently consists of
UF engineer A. Madorsky as well as engineers V. Golovtsov and L. Uvarov
from the St. Petersburg Nuclear Physics Institute, who assist with the
hardware design, construction, and test. Madorsky is presently supported
50% by Project funds and 50% by the University. He oversees all
technical aspects of our trigger work. The other engineers are part of a
team from the St. Petersburg Nuclear Physics Institute (PNPI) headed by
Golovtsov and hired temporarily at Florida entirely from Project funds.

## CMS Base Program Enhancement at UCLA

*Prepared by J. Hauser and R. Cousins*

**Responsibilities:**

The UCLA \"Task E\" group works in the TriDAS and EMU subsystems of CMS.
The present mix of US-CMS Project and DOE base program funds is adequate
for the tasks we have taken on, however it is important that these be
maintained at a constant level of effort during the coming year. Prof.
J. Hauser is for CMS the CSC Trigger Project Manager and for US-CMS is
the L3 manager for the EMU trigger in Tridas. Prof. R. Cousins
previously constructed the Sector Receiver board for the successful
Track Finder prototype in FY00, and is now working on development of
software algorithms for triggering on muons together with a postdoc and
a graduate student both resident at CERN. UCLA takes responsibility for
trigger primitive software for the endcap muon system. Hardware being
built by UCLA includes anode and cathode trigger boards. The anode
trigger boards are heading into full production as soon as the
validation of the design is finalized, while the schedule for cathode
trigger boards calls for full production to start about one year later.

**Scientific Staff:**

Dr. von der Mey works full time on the development of software and
firmware associated with the CSC trigger electronics. During the next
year on-chamber trigger electronics is going into full production, and
the off-chamber trigger electronics design is being finalized. Top
priority is given to validating the design of the on-chamber
electronics, which is now on the critical path for the EMU system and
will be entering the production stage as soon as the design is fully
validated. The software support includes trigger primitive simulation,
simulation of electronics \"firmware\", and readout for bench testing as
well as cosmic ray testing after installation. These are tasks requiring
expertise of a physicist to guide the engineers. Dr. von der Mey is
fully supported by the DOE base program. Continuation of this support is
vital.

Dr. Lindgren works part time on supervision of production and testing of
CSC trigger boards and cables (he is also Associate Head of operations
for CDF). We expect to take advantage of Lindgren\'s prior expertise in
large-scale production for CDF to address issues that will come up due
to the large numbers of CSC trigger boards (about 500 each for anode and
cathode types). He is presently mostly supported by UCLA physics
department funds, therefore at present his continuing support is not an
issue.

**Technical Staff**

UCLA engineers that work on this hardware are J. Kubic and Y. Shi. Kubic
is supported by the project (mostly EMU), while Shi is mostly supported
by the UCLA physics department. Three additional PNPI visiting engineers
(Iatsioura, Kan, Zhmakin) are involved as well. Iatsioura is responsible
for ALCT construction and prototype testing. Kan is responsible for
layout of three ALCT variants. Zhmakin is responsible for production
testing. These engineers are part of a team from the St. Petersburg
Nuclear Physics Institute (PNPI) headed by Golovtsov and hired
temporarily at UCLA entirely from Project funds.

## CMS Base Program Enhancement at Rice

*Prepared by J. B. Roberts, P. Padley, B. E. Bonner*

The HEP group at Rice has taken on a number of responsibilities within
the CMS project and these are likely to grow in time. As detailed in our
MOU with CMS, we expect to build parts of the endcap muon electronics
and parts of the trigger electronics. To be explicit, we are in both the
EMU and TRIDAS subsystems. We are responsible for the "EMU Trigger
Motherboard" (EMU electronics), "EMU Trigger Port Card" (TRIDAS) and the
"EMU Trigger Clock and Control Board" (TRIDAS). In addition we have
taken responsibility for timing and synchronization issues for the
endcap muon system.

It is likely that we will be expected to take on other commitments as
well. In particular, the responsibility for integration issues regarding
the endcap RPC system is one that would be natural for us to assume.
While the endcap RPCs are outside the US responsibility, the US has
overall management responsibility for the endcap muon system, hence the
need for someone to be responsible for RPC integration issues. In
addition the possibility of a trigger data link between the RPC and CSC
systems will be proposed in the near future. This very attractive option
would expand the amount of work expected from us.

We now describe enhancements to our base program that are necessary if
we are to complete the tasks in our MOU. Without these enhancements one
must worry that these key components of the US contribution to CMS could
be in jeopardy. Here we are not including the possible expansions of our
responsibilities mentioned above. It is clear that we must be able to
successfully complete our currently assigned tasks before taking on
additional responsibilities. We give below what is required to
accomplish that.

**Scientific Staff:**

Within our MOU with CMS, the project plan shows that we need typically
1.5 post-docs working on CMS in any given year. This is split between
trigger and EMU electronics work. We believe that in order to properly
complete our work on CMS, the addition of a post-doc to our group is
essential. This post doc would work on a number of things, including
simulation studies of our designs and the testing of prototype hardware,
the design of the final electronics and the installation at CMS.

**Technical Support Staff:**

The MOU shows technician time at various points in the schedule.
Presently we can not afford to keep a technician on staff. While it is
possible to use undergraduate students for this work, it would be better
if we had a full time technician on staff. Unfortunately we can not hire
a technician with the amount of funding we receive for this work from
CMS.

**Travel Budget:**

Our participation on CMS requires a significant increase in our travel
budget. While we try to minimize travel to Europe, a fair amount of
travel to CERN is inevitable.

**Rice Base Program Budget Enhancement Request:**

1\. Postdoc 50K

2\. Travel supplement 15K

Total 65K

## CMS Base Program Enhancement at Wisconsin

*Prepared by W. Smith, D. Reeder, R. Loveless, S. Dasu*

The Wisconsin group works in the TriDAS, EMU and Common Projects
Subsystems. Prof. W. Smith, CMS Trigger Project Manager and US CMS L2
manager for the trigger, leads US CMS L3 manager for the calorimeter
trigger, Assistant Professor S. Dasu, Assistant Scientist P. Chumney,
Postdoctoral associate F. Di Lodovico and engineers J. Lackey, P. Robl,
M. Jaworski and technician R. Fobes in the construction of the regional
calorimeter level 1 trigger. Senior Scientist R. Loveless, US CMS Common
Projects Level 2 manager and EMU Technical Coordinator, along with
Profs. Don Reeder and D. Carlsmith and postdoc S. Lusin (100%) are
responsible for the endcap steel yoke, the EMU chamber low voltage
power, cooling, infrastructure, mounting and installation. Engineering
and other support is provided through CMS project funding of personnel
at the University of Wisconsin Physical Sciences Laboratory on a full
cost recovery basis.

**Scientific Staff:**

Dr. Chumney works full time on the trigger simulation, software support
of the trigger hardware testing and operation and assists the engineers
in the design and testing itself. Over the past year, she developed the
interface specifications between the calorimeter regional trigger and
the ECAL and HCAL readout electronics, and with the Global Calorimeter
Trigger. She finalized the calorimeter trigger tower mapping. She wrote
all of this up in a series of CMS Internal Notes. She used the ORCA
simulation to produce all of the calorimeter trigger efficiency and rate
plots and tables for the CMS Trigger TDR.

Dr. Lusin performs EMU system design studies, supports chamber
construction at Fermilab and works on general installation and
infrastructure design. He is in charge of EMU system electro-mechanical
integration at Fermilab and supervises an engineer on this task. He
coordinates electronics installation and noise testing. He is leading
the development of the EMU low voltage system based on 400 Hz AC/DC
converters that is likely to be widely adopted in CMS. Dr. Lusin is also
in charge of the EMU cabling plan.

S. Dasu was a scientist in the group recently and was responsible for
CMS calorimeter trigger simulation and conceptual design. He has now
taken a Wisconsin faculty position and the Wisconsin group must add a
post-doc to fulfill CMS obligations, in particular to continue the
physics simulations for validating the calorimeter trigger design and
complete design of tau and jet trigger hardware. Therefore, the
Wisconsin group hired F. Di Lodovico, who works 50% time on the CMS and
BaBar experiments, for the period April 2001 to April 2002, supported
using S. Dasu\'s start-up package from the UW Graduate School. She has
begun studying trigger efficiency for higgs particles produced in vector
boson fusion. Her job is to improve the level-1 trigger efficiency for
those higgs boson decays into b-quark jets, and to develop software for
higher levels of trigger and analysis. She will develop b-quark tagging
techniques that will be useful for this and other analyses. A 0.5 FTE
post-doc for this task is an important investment in preparation for CMS
data taking.

The UW group has been collaborating with the CONDOR group headed by
Prof. Miron Livny of the UW Department of Computer Science to run a
distributed computing facility for CMS. With seed money from the UW
Graduate School the Wisconsin group set up a 2 TB storage server in the
UW HEP group computing facility and leverages use of a 1000 CPU farm
maintained by the CONDOR group. The UW Graduate School also funded a
Computer Science graduate student to aid in technical aspects of running
this system. Wisconsin is now part of the CMS worldwide simulation
production team. However, the group needs a 0.5 FTE post-doc effort to
both fully exploit the existing facilities at UW and to develop it as
part of an international computational grid. The facility should develop
into a Tier-2 computational center for CMS.

**Technical Support Staff:**

The UW lead engineer, Joe Lackey, works on CMS full-time and is
supported 50% on the base grant and 50% on the CMS project. Mr. Lackey
is one of the top US HEP electronics engineers with considerable
experience in delivering state of the art high-speed massively parallel
trigger systems, such as the Zeus calorimeter trigger. He will be
required on staff through CMS startup and operations. The engineering
budget for the CMS calorimeter trigger was reduced to the absolute
minimum required in the course of the descoping. Having the lead
engineer full-time supported on the base program will allow earlier
introduction of increased engineering resources and will address the
problem of continuity of support as the project moves into the
operations phase.

The UW CMS MOU shows technician time at various points in the schedule.
Presently UW cannot keep a technician on staff. We intend to use
Physical Science Laboratory Staff for technical work. This is an
expensive option and will easily saturate the funding for technician
time that is budgeted for TriDAS, EMU and CP tasks. It would be more
cost effective to provide for a technician within the base program. The
continuity of a single technician employed on the base program will also
reduce costs associated with training and instructing technical support
from PSL. There is a significant amount of technical work required at U.
Wisconsin for CMS for the next few years. For the EMU system, there is
general infrastructure support, including tests of thermal conductivity
for the cooling system, assembly and testing of low voltage power
supplies, testing of magnetic shielding for the DC-DC converters,
coordination of cooling system procurement and production, supervision
of cooling system delivery to FNAL, PNPI, IHEP, supervision of frame
production and delivery to FNAL and coordination of LV procurement and
delivery to CERN. For the support of Wisconsin effort at FNAL factory,
there supervision of assembly of frame and mounting brackets at factory,
supervision of assembly of cooling system at FNAL, and general support
for Wisconsin postdoc at cosmic ray stand. Eventually, for the support
of the Wisconsin effort at CERN, there will be installation and
maintenance of chambers, installation and checkout of LV system,
installation of cooling manifolds, cables, etc. and supervision of
installation of CSC mounts on iron disks. For the work on the
calorimeter trigger, we need a technician to work on assembly and test
of the prototype electronics, preparation of modifications of printed
circuit boards with surface mount devices, general assembly of
electronic components, mechanical assembly of electronic chassis and
crates, cabling, inventory of parts and maintaining supply cabinets,
parts ordering, maintenance and repair of test setups, soldering and
desoldering, assembly of cooling, and testing of power supplies. While
this is much more work than can be done by one technician and is
budgeted as such, this list of tasks shows how a single technician
employed by the base grant will make an important impact on reducing our
costs and increasing our productivity.

**Travel Budget:**

In his role as CMS trigger project manager, a member of the CMS
Management Board and Steering Committee, and the US CMS Data Acquisition
and Trigger Level 2 Project Manager, W. Smith is required to attend a
number of CMS meetings at CERN each year. As CMS Endcap Muon Technical
coordinator, US CMS Muon Technical Coordinator and US CMS Common
Projects Level 2 Project Manager, R. Loveless also has to make a number
of overseas trips each year as part of his duties. In addition, W. Smith
and R. Loveless are required to participate in a number of site visits
and reviews in the US. In addition, S. Dasu, as Level 3 US Calorimeter
Trigger Project Manager, S. Lusin, P. Chumney and F. di Lodovico also
need to travel to CERN. This travel expense has led to a chronic 20K
shortfall in the travel budget each year.

**1.3.2 DAQ:**

We request that one full-time postdoctoral associate be hired by UCSD to
work on High Level Triggers. With Jim Branson continuing as US CMS
physics coordinator, and the increased effort on the new reconstruction
software, there will be a lot of synergy between the HLT work and the
associated physics work. The addition of a suitable person would benefit
directly both efforts. The committee reviewing the US DAQ effort has
again noticed the need for additional physicist time on the DAQ.

The HLT work is at this point truly urgent, and US participation in it
is at best lagging behind the rest of CMS. It is imperative that US CMS
participates more actively in this area of work. In order to not dilute
the request in any way whatsoever, this is again the only request put
forth by the DAQ system for FY2002.

For the last two years the DAQ project, following the recommendation of
the review committee (Lehman review) had requested postdoctoral
associates to work on the High Level Trigger algorithms. The request was
not yet satisfied by DOE. Last year the request was given very high
priority by US CMS. We hope that this urgent need can be met early this
year.

4.  **ECAL:**

. The first laser has been now been delivered to CERN and the 400
channel crystal module and the 1700 crystal supermodule will be brought
online at CERN in 2002 and 2003 respectively. The ECAL community is
faced with an enormous task and is severely lacking in the physicist
manpower for the execution and analysis of these tests. The Caltech
group has been very effective at bringing this laser light source online
at CERN and are well positioned to make a significant contribution to
the effort. This physicist will lead in the following areas:

1\) Oversee the day-to-day operations of the laser in the 400-channel
module test beam effort.

2\) Prepare the analysis tools to analyze the monitor data.

3\) Analyze and understand the data collected for the
monitor-calibration system.

4\) Take a leading effort in analyzing the data taken during the
calibration runs.

5\) Prepare the analysis tools for the supermodule calibration in the
coming years.

5.  **FPIX:**

Unquestionably Fermilab is playing a major role in the construction of
the Forward Pixels with its physicists and by allowing us to utilize the
Silicon Detector Facility . This is true at the present time, but it is
uncertain if this facility will still be accessible to us when the
construction of the US-CMS pixels takes place. The projected research
program at FNAL foresees a very heavy use, over the next few years, of
SiDet for upgrading the vertex detectors of CDF, D-Zero, and for the
pixel detector for BTeV. It is indeed questionable which resources will
be available to US-CMS to complete the R&D and to then assemble the
pixel detector in FY '04 -- '05. To secure the timely assembly of the
US-CMS pixels, new resources must be secured to carry out a certain
number of tasks. This unique situation lead us to the following request
for the HEP base program of DOE.

**Increased base support for the Miller/Shipsey Group at Purdue.**

Profs. Ian Shipsey and David Miller with, along with their group at
Purdue University, have recently joined the US-CMS pixel effort. They
have committed their team to working on the assembly of the pixel
detectors ("Plaquettes"); the most critical components of the detector.
Their group is also contributing to many other tasks, among them
mechanics. The Purdue group has recently completed the construction of
the silicon detector system for CLEO. This was possible because of the
unique resources they have assembled at their institution, with the
support from their base program and their University. This includes a
large clean room of 3000 sqft, of Class 10,000, a wire bonder, CMM
machine, numerous storage cabinets for silicon devices, and a variety of
test equipment. (This space is adjacent to a clean room where Prof.
Daniela Bortoletto's group is characterizing the silicon pixel detectors
for US-CMS.) The Shipsey/Miller facility has been operated by a superb
engineer, Kirk Arndt, and technician Tom Smith, both supported by their
base program, DOE. It is this uniquely qualified manpower, together with
the facilities, that have allowed the construction of the CLEO3 silicon
detector. Given the uncertain availability of SiDet, I believe that we
must have access to these resources at Purdue University and add the
contributions of the physicists in this group in order to secure the
timely construction of the US-CMS pixel detectors. The Miller/Shipsey
group is asking DOE to restore the full base support for the manpower
associated with the silicon assembly facility. This includes the
engineer, Kirk Arndt and the technician Tom Smith. In support of our
request I list the following facts:

-   The demonstrated very strong leadership of this Purdue group.

-   The existing first-rate assembly facility of silicon detectors
    (state of the art equipment and demonstrated outstanding manpower),
    financed mostly with base support.

-   Strong support for this physics group from the University.

-   Easy access to a large pool of students, an inexpensive, highly
    motivated manpower very helpful in assembly jobs such as those
    needed to build the US-CMS pixel detectors. Strong impact of this
    project in the education of students.

Requested funds for Purdue (Miller/Shipsey) -

Starting in: FY02 \$80.0K for full base support of Kirk Arndt and Tom
Smith

> Total requested funds: \$80.0K

**1.8 SiTrk:**

UC Santa Barbara

A major UCSB production line for US CMS requires only the of one
post-doc in FY02.

This post-doc is needed to assist in the setup of test stands and other
production equipment. Engineers, designers, students and faculty will be
in place already from the existing base grant. Equipment and space, can
be covered on existing funds without the use of Project contingency.

##### Because deliveries of components have slipped, production at FNAL is expected to overlap with CDF and D0 upgrades for Run 2b.

##### Therefore we plan to establish a "contingency production line" at UCSB It will be responsible for assembly, wirebonding and testing of \~1700 modules. This line helps to alleviate conflicts with CDF and D0 Run2b silicon projects at SiDet which will likely occur at the same time.

##### Kansas

Presently Profs. Alice Bean and Phil Baringer are members of the CMS

group. New Assist. Prof. Graham Wilson is considering participating

in CMS in the future. We are working with the Tracker Outer Barrel

group to help test and produce modules at the Fermilab facility. We

have taken responsibility for ensuring that the electronics test stands
to

test hybrids and modules provide the needed functionality. Currently we
have

2 postdocs who are involved with the CMS project: Len Christofek is

located at Fermilab and will spend 50% of his time on the CMS project,
Xin Zhao

is located at University of Kansas his fraction of commitment on CMS can

be up to 50%.

For 2003-2005, we would like to have the equivalent of one full

time postdoc on CMS which is actually split between the two postdocs.

Both of these postdocs would be located in the US with one in residence

at Fermilab. For this timescale we will involve students in the
construction effort

at Fermilab. In addition, we have an electronics technician resident at

Kansas who can be called to work on the CMS project as needed.

We will need appropriate travel funds available in our grants in order

for us to transport personnel between Kansas and Fermilab. At present,

our grant only provides enough travel funding for a few short visits a

year. If visits up to a month or more are needed we will scramble for
money to

pay for them as our NSF base grant does not have funds to cover

this type of travel. During this period, we see most of our effort

going towards the construction of the Tracker Outer Barrel.

Starting in 2005-2006, we would like to hire a postdoc full time

on CMS that would be located at CERN. We would also like to

locate students at CERN for a year at a time when data taking

commences. In addition to this CERN presence, we would like to be

fully involved in the physics analysis as much as possible in the US

.

We understand that there will be regional centers here in the US for
this

effort. We would travel to these regional centers as necessary for

this effort in addition to doing as much as we could at Kansas.

At this point, if our NSF base grant funding is the same as it is

currently, we would be unable to afford any personnel at CERN.

### SWC

Stephan Wynhoff -- Princeton (David Stickland)

In Stephan\'s case, he has taken over my role as leader of the

reconstruction effort, a cross-project group between the Computing and

PRS group. He is deeply committed to doing excellent work, and is the

prime contact for all the users of the software. Almost single handedly

he has organised, put together and given the widely attended ORCA

courses (there was one last year at FNAL and we plan one later this year

possibly on the west coast). Support for Stephan translates directly

into support for the US Physics program, and for the CMS physics

program. This is a first class postdoc doing work that the experiment

depends on and is a natural part of a strong University base program.

PD -- Northeastern (Lucas Taylor)

Support for a postdoc would be instrumental in linking the PRS groups to
the SWC tools developed by the NEU group.

we are short a software-wise physicist (postdoc)

to work with the PRS groups to ensure they are being adequately

supported with the new analysis methods (where we have software

engineering expertise already).

Tasks would include (obviosuly to be refined with Paris, et al):

\-- defining, implementing, and supporting useful TAGS (ntuple-

like structures with pointers into the full event) for the

four PRS groups as they require, in a coherent fashion.

\-- deploying and integrating the new tools (Lizard, Anaphe,

perhaps ROOT, and so on) where previously ntuples and PAW

were used

\-- working with our (\"physics-innocent\") graphics experts to

ensure the event display is really focused on PRS needs.

There are clearly many more such items which will come up as time

goes on; this is already a lot for one person.

At Northeastern we would dearly love to fund this postdoc but simply

do not have sufficient funds.
