**INTEGRATED CONTROL SYSTEM**

**March 2001**

# I. Senior team leader assessment

# 

The Senior Team Leader Assessment is for the month of March, 2001 only.
The full narrative which follows covers the months of February and
March, 2001.

# Technical and programmatic Progress and Accomplishments

#### Integrated Control Systems 

-   Chris Tremel has been added to the LANL controls team as a Post
    graduate student, and Chris Allen has completed all of his
    interviews and should be on board next month.

-   Peregrine McGehee will transfer into the LANL SNS division and work
    with us 75% for the remainder of the year.

```
-   Participated in the Conventional Facilities design reviews at San
    Francisco to ensure that control system requirements are met.
    Prepared and submitted an integrated communications \"backbone\"
    cable plan to the AE. This will enable the AE to (a) size
    communications duct banks and (b) design the cable plant required.

```{=html}
<!-- -->
```
-   Supported Final Design Reviews for the DTL and CCL vacuum systems,
    and the DTL and CCL high power transmitters.

-   Attended the Final Design Review for Beam Position Monitors. The
    control involvement in the low level to provide a server for
    time-stamped data is also done. Further involvement in diagnostics
    is not yet defined. High level requirements are not yet complete.

```{=html}
<!-- -->
```
-   A fully-prototypical and functioning PID control loop has been
    implemented in the Cryo Control Development System. This is a
    significant achievement for the Integrated Control System
    Development. It is the first end-to-end implementation of a control
    loop utilizing the standard ICS hardware, software, and operator
    interface screens.

-   Several vendors have provided informal estimates on providing the
    PPS PLC equipment for the LINAC segment (the first segment to be
    installed).

-   A design has been proposed for the PPS controls of the primary
    shutters in the target building. A series of key locks will be
    provided which will enable the operator to close and secure the
    shutter in the closed position. This feature would be used for
    example when neutron beam line shielding required maintenance.

-   The SNS beam synchronous encoder prototype module register functions
    have been tested at BNL under VxWorks. Its EPICS driver is under
    development and will be tested against the SNS event decoder
    prototype module in April. EPICS drivers for both modules will be
    released in May.

-   EPICS drivers are being written for the BNL power supply
    controllers, and hardware checked out. Some stability testing on the
    DAC and ADC, and some accuracy testing of the DAC has been done.
    Test results are shown below. Drift with time and temperature is low
    and DAC accuracy is very good. The ADC accuracy is yet to be
    measured. We installed a GPIB interface to a multimeter and provided
    a labview interface to accurately measure input and output voltages.
    The tests are done using the serial interface port to the PSC. This
    port can be used to do power supply testing where EPICS support is
    not available.

-   Hardware test stands for the Linac LLRF board development and hot
    model vacuum system are operational at LANL

```{=html}
<!-- -->
```
-   The controls group has set up Linux/EPICS environments for the use
    of the Accelerator Physics and Diagnostics groups.

-   A complete protocol for control system back-ups was initiated. The
    back-up administration is handled by Jim Simmons from the ORNL
    Workstation Support Group. Incremental Back-ups are performed every
    night Mon-Sat. Full Back-ups are done once a week on Sundays.

-   The controls group has arranged a collaboration with John Sinclair
    of the Holifield Accelerator (ORNL) to help in the development of
    EDM -- the display manager selected by SNS and developed by John.

## Variance Analysis And Project Cost Performance Reports

> **WBS 1.1 R&D**
>
> **Variance Statement:** No Variance, work is complete.
>
> **Project Impact:** No impact.

**Corrective Action:** None required.

> **WBS 1.9 Integrated Control Systems**
>
> **Variance Statement:** Significant variances exist in several areas.
> This has occurred for the following reasons:
>
> WBS 1.9 had a negative schedule variance of \$1298.3K and a negative
> cost variance of \$317.5K at the end of FY00.
>
> The schedule variance was due to not assigning personnel. This was due
> to some Title II Design and software design work not being assigned
> because requirements were not developed by other systems soon enough
> and difficult in hiring software engineers due to the Low Energy
> Demonstration Accelerator (LEDA) and the Relativisitc Heavy Ion
> Collider (RHIC) projects at LANL and BNL not releasing personnel to
> SNS on the expected schedule.
>
> The cost variance was due to charges in level of effort activities not
> matching BCWS (which causes an artificial variance because BCWP = BCWS
> for these activities by definition) and to a retroactive SNS labor
> rate change in August which caused cost for which there was no earned
> value produced.
>
> Since the BCWS for FY01 is the \$9500K authorized BA for FY01, the
> FY00 schedule variance cannot be overcome.
>
> Difficulties in transitioning FY00 data and loading FY01 funding
> package data into the new MPM system has caused the BCWS in FY01 and
> BCWP for FY00 to be in error. This is causing false variances.
> Presently, all BCWS errors have been corrected and BCWP contains
> errors in only a few places.
>
> In FY01, the schedule variance continues to grow. This is due mostly
> to planned procurements being delayed and the cost cutting exercise
> causing requirements to change and arrive at a slower pace. However,
> obtaining personnel at a rapid enough pace is still a problem.
>
> **Project Impact:** No project impact has occurred.
>
> **Corrective Action:** An aggressive hiring program was started
> several months ago and will continue until all needed software
> personnel are obtained. LEDA and RHIC have recently begun transferring
> personnel to SNS and several personnel have joined the team.
>
> Work to correct Primavera data and MPM calculations is expected to
> resolve inconsistencies in the near future. After MPM calculations are
> correct, a PCR will be processed to remove the artificial variances
> that have occurred.
>
> Variance statements are provided below where they exceed thresholds.
> Until MPM data has been corrected, data accompanying these statements
> will be obtained by taking BCWS and ACWP from MPM, and taking BCWP
> from manual calculations based on the monthly progress status of the
> Primavera detailed schedule.
>
> Planned procurements will be placed in the near future.

**3.3 PROJECT CRITICAL PATH ANALYSIS**

> R&D for controls consists of small effort to complete some software
> drivers and evaluations of some vendor hardware. This effort is nearly
> complete and was neither near the project critical path nor a
> controlling activity within WBS 1.9
>
> The strategy for line item work is to have all hardware and software
> for WBS 1.9 elements tested to the degree needed to support technical
> systems commissioning prior to its being needed. Thus, WBS 1.9 would
> not lie on the project critical path.
>
> At present, no WBS 1.9 activities lie on the project critical path.

### **Technical Progress/Accomplishments**

## (This WBS element covers the management costs for WBS 1.9, including the salaries of the Senior Team Leader and Lead Engineer.)

A very successful cabling workshop was held at LANL to review
Conventional Facilities (CF) 75% review package drawings, finalize plans
for conducting cabling work, and resolve many outstanding issues. An
improved design for cable trays in the Klystron building was developed
at the workshop. A draft report has been issued for comment.

Numerous detailed cable listings were received and used to generate new
cost estimates for both CF and Accelerator cable trays. This cost data
will be used to support installation planning.

Data entry and cleanup of discrepancies in the new MPM system was nearly
completed. In April, schedule status data will be examined in detail to
confirm proper BCWP calculations in MPM.

The CF controls impact on CF system design changes recommended to reduce
cost was evaluated. A more accurate method of estimating cost has
resulted from this and revised costs should be available soon.

A draft interface control document defining CF controls interfaces to
mechanical and power equipment was generated.

Significant progress was made on the software development environment
infrastructure (tag naming conventions, logical connections between PLCs
and IOCs, etc.).

Completed the procurement process for both 7-slot and 21-slot VME
crates. The next step will be to evaluate first-article units when they
become available (in a June timeframe).

The cabling Systems Requirements Document (SRD) was signed. This
completes all technical baseline documents for controls.

A decision to continue with the present Control Logix/EPICS architecture
was reached.

A restart workshop was held to plan for starting Title II design and
software development activities. All activities were stopped while the
architecture was being reviewed. The present Title I cost estimate was
reviewed and found to be adequate, agreement was reached on the
methodology for developing new deliverable dates and, decisions
concerning many design details were made. New schedule dates will be
developed in March.

Cable counts for all cabling in the Front End, Linac Tunnel and Klystron
Building (FELK), the Ring tunnels, and the Ring Service buildings were
completed and appropriate data delivered to the AE/CM. Agreement on a
division of work between the AE/CM and SNS for design and installation
of cable tray in these buildings was reached. A mini-workshop on cabling
is planned for March 20, 2001 at LANL. Arrangements for who will provide
cable tray design in areas where the AE is not providing it will be a
major topic at the workshop.

Data entry and cleanup of discrepancies in the new MPM system continued
and was intensified in order to bring the system into operation for
controls more quickly.

Preparations for an "Ed Temple" cost and schedule review of the controls
subproject were completed. The review was postponed but preparations
were valuable in showing the team where we are and in highlighting some
issues that need attention.

## **B. [WBS 1.9.2 Global Control System Subsystems]{.underline}**

### **Technical Progress/Accomplishments**

**WBS 1.9.2.1** (Network)

The control system network architecture has been revised to provide
network switches out on the service building floor. This will greatly
reduce the amount of cabling required and should improve noise immunity
(due to extended use of fiber optics). This newly proposed network
architecture was presented to ASAC in February, and strongly endorsed.

A Controls System Network Switch proto-type (CISCO 6509 Core Router,
CISCO 3508 Gigabit Concentrator, and CISCO 3548 10/100 VLAN) was
installed in the controls area at ORNL. This hardware is on loan to us
from CISCO for 60-days, and is being set up to correspond to the SNS
global controls network design. This switch (pictured below) is now
operational. It will ultimately become the core switch for the control
system network.

**WBS 1.9.2.2** (Global Timing)

Beam synchronous decoder (V124S):

The prototype PCB has been assembled at Brookhaven. Testing is well
along and all major functions have been tested and are working. Some
minor PCB changes are required, but overall, the module is working. The
front panel remains to be fabricated. Refinement to the gate array
functionality continues. A second prototype is under construction. Some
minor clarifications to the V124s module description has been written in
preparation to the software driver work beginning. We do not plan to
release this design until after the design review this summer. This task
is on schedule.

Beam synchronous encoder (V123S):

A prototype eventlink master remains set up in the SNS controls lab for
driver development. Register functions have been tested under VxWorks.
Its EPICS driver is under development and it will be tested against
V124s -- (SNS event decoder prototype module) in April. EPICS drivers
for both modules will be released in May. Assembly of additional
prototype V123s modules is underway.

RTDL Encoder (V106):

The parts list for the RTDL encoder referenced BNL part numbers. This
month the parts list was updated to reference manufacturers part numbers
and the parts list was sent out to a distributor to get a quote on
kitting the parts. Once the quote is in, we will have a better idea of
the delivery schedule for the components.

Using RHIC spares, we are setting up an RTDL system at BNL for software
development.

SNS Timing/Event System Test Stand

**WBS 1.9.2.3** (Machine Protection)

Design for the Logic in the Altera 10K70 chip for the MPS system is
underway.

**WBS 1.9.2.5** (Global Software)

-   An audit of "Channel access v3.14 was completed to verify data
    object is thread safe.

-   EDM object completed to share connections to Process Variables in
    channel access. (EDM is the display editor/manager tool selected for
    use on SNS.)

-   The Archiver was modified to ignore future time stamps that come
    from Labview on initialization. The archiver web browser now allows
    user to export Matlab format files.

-   A good start was made on a technical database model for SNS systems.
    Work has started on the lattice, magnets, power supply and cryogenic
    systems. Eventually, information related to all control system
    signals will be in this database, and the database will be used to
    generate the distributed EPICS configuration databases, from which
    the control system will operate. This is a very large undertaking,
    and help from the project office is recognized and appreciated.

-   The new EPICS "Data Object" is complete and tested. Performance
    tests show that using this data object in C++ will require less than
    1 usec per channel to copy into buffers for clients that do not
    request conversions. This new Data Object is the basis for the new
    portable server, which will become the only EPICS channel hccess
    server. This will allow us a platform to support many of the event
    and composite data needs that we are not able to provide in the
    current channel access server, and is the basis for most of the
    future enhancements required for SNS.

\$1698.3K \$1333.2K \$1342.1K (\$364.9K) (21%) (\$8.9K) (1%)

1.  **Problem Statement:**

This variance is due the FY00 variance described in Section I and not
receiving costs for equipment orders placed in November. Essentially,
FY01 work is proceeding nearly as planned except for equipment
procurement.

2.  **Potential Project Impact:**

No project impact is expected. FY01 work is planned such that the work
not completed in FY00 will be caught up by the end of FY01.

3.  **Corrective Actions:**

No corrective action is needed. The FY00 variance will be corrected as
stated in Section I. Equipment orders will be placed soon.

## **C. [WBS 1.9.3 Front End Control System]{.underline}**

Executive Summary:

Support of daily operation of Source/LEBT continues. Title II for MEBT
power supplies completed. Progress continues to migrate EPICS software
to standard Applications Development Environment (ADE). Orders are
complete for all Vacuum/Utility interface hardware. A review of Front
End controls architecture and of EMI/RFI issues was held.

Progress continues in migrating Front End EPICS software to the SNS
standard Applications Environment. All Vacuum interface equipment is on
hand; significant progress was made on RFQ vacuum. All MEBT interface
hardware except Rebuncher RF is on order\--most on hand). The BNL
controls team participated in the collaborative definition of
specifications for the replacement Display Manager (\"EDM\").

A test was conducted in which the front end control system was viewed
"live" from Oak Ridge, using the EPICS PV Gateway.

[1.9.3.1: Front End Controls Integration/Management.]{.underline}

Effort continues to complete loading of code repository at SNS/ORNL;
both Front End specific applications and LBL-enhanced versions of EPICS
tools are being addressed. FE work is now done entirely from the new
repository. As experience is gained, the ADE template is refined. GDCT
is now available on both Linux and Solaris.

Mike Thuot (LANL) and Ernie Williams (SNS/ORNL) reviewed the overall
architecture of the Front End controls, and also reviewed the shielding
and grounding of the existing Source/LEBT.

The BNL Controls team Collaborated on the work to define specifications
for EDM, the replacement display manager to DM2K.

[1.9.3.2: FE Controls Ion Source/LEBT.]{.underline}

Based on the review by Thuot/Williams, all problems caused by sparking
and corona during operation have been mitigated. Additional work will be
done to protect against even rarer events.

Support of daily operation or Source/LEBT continues.

Packaging of the controls interface to the DTI -65kV power supply began.

[1.9.3.4 FE RFQ]{.underline}

(No activity.)

[1.9.3.5 FE MEBT]{.underline}

### **Technical Progress/Accomplishments**

**WBS 1.9.5.1** -Ring Controls Integration

Dave Gurd and Bill Devan from ORNL were at BNL this month for 2.5 days.
There was a review of the project status for power supplies, Vacuum, RF,
Timing, Diagnostics, Database, Naming conventions and application
software.

We have set up equipment in the lab to test timing boards. We have
received assistance from CA personnel to demonstrate that the new timing
board is operational before developing Epics driver software. We are
using some CA hardware to build a system that will enable testing the
hardware. The development of timing driver software has started.

Documentation for the SNS/BNL naming convention and database entry is
being written. We are continuing to update the Naming and optical
database.

BNL has been working with ORNL on the setup of the ADE and new server at
ORNL.

BNL is working with ORNL on the setup of the ADE and new server at ORNL.
Ernest Williams will come to BNL in April to assist in making the
development environment at BNL the same as ORNL. In addition he will
help in the transition from the Sun environment to Linux and with the
installation of new software such as EDM.

BNL plans to order an extra server on the cluster that will be used for
Linux software testing. This is a very low cost approach, is extendable
and requires very little resources, (disk space, backup services etc.)
because it bootstraps on the present cluster work.

**WBS 1.9.5.2** - Power Supplies

PSI/PSC:

In February, BNL received a prototype of the PSC and PSI boards for
testing. a problem with the fiber optic receiver logic was detected, and
subsequently corrected by the manufacturer (Apogee). EPICS drivers are
being written and hardware checked out. Some stability testing on the
DAC and ADC, and some accuracy testing of the DAC has been done. Test
results are shown below. Drift with time and temperature is low and DAC
accuracy is very good. The ADC accuracy is yet to be measured. We
installed a GPIB interface to a multimeter and provided a labview
interface to accurately measure input and output voltages. The tests are
done using the serial interface port to the PSC. This port can be used
to do power supply testing where EPICS support is not available.

height="3.7645833333333334in"}

Ethernet Digitizer & Function Generator:

We have been contacted by KEK and they indicated that by contract they
are no able to provide us with the source code for the Yokogawa
instruments we anticipated using for the injection power supplies. BNL
and KEK will both try to contact the factory to see if some arrangement
can be made so we can obtain the source. If unsuccessful we will work
with the power supply group to choose alternate instrumentation. This is
not expected to be a problem except we will likely have to give up on
the Ethernet interface.

Software Development:

There was a meeting in February with Dave Gurd and Bill Devan from ORNL
to review the developments in the power supply and other areas. The
EPICS driver is under development and approximately 50 percent complete.
There are some hardware issues but it is expected the impact on the
software will be small so software development is proceeding. EPICS
driver development extensively tests the VME interface.

**WBS 1.9.5.3** -- Diagnostics

In February we were able to implement the controls for the LeCroy scope
from a PC using Labview and portable channel access server software.
Next month we will add software to run a motor controller on the same PC
using Labview.

Meetings with the diagnostics team have resulted in a plan to jointly
develop ICDs, with the BLM ICD serving as a prototype.

The BNL Controls Team is providing assistance to the diagnostics group
in the setup of development PCs and software. A system for the wire
scanner, which includes the PC, NT, Labview, motor controller hardware
and software, has been set up and is now ready for diagnostic
development.

**WBS 1.9.5.4** -- Vacuum

The Preliminary Ring Vacuum ICD, "Spallation Neutron Source Interface
Control Document 1.5.5 Ring Vacuum System and 1.9.5 Ring Controls" has
been completed and waiting for group leaders' signatures. (

>
> Fig 5. Preliminary SNS Ring Vacuum ICD

There was a vacuum meeting at JLAB in February. The purpose was to
review the hardware used at JLAB and determine if it was suitable for
the whole SNS.

The Vacuum controls lab at BNL was upgraded by adding some real vacuum
components. This will help in the development of controls in a few
months. Serious work will wait until the controller interfaces have been
defined and some test controllers have been purchased.

**WBS 1.9.5.5** - Application Software.

# UAL 2.0: Online SNS Simulation Facility:

A demo of the SNS Ring Application Manager with MEDM-based Power Supply
Applications was implemented. This demo is designed after the NSLS
Application Manager and Windows Explorer and aims to consolidate and
organize heterogeneous engineering and commissioning applications (e.g.
MEDM screens, Java packages, scripts, etc).

Installed and tested the JCA (Java interface to Channel Access) package
on the sun1.sns.bnl.gov server. In addition, the small demo has been
implemented to test the JCA package with Swing Components in the
multithreaded environment. The demo is designed to access data from the
Power Supply Simulator IOC.

BNL worked with the ORNL Accelerator Physics team studying effects of
impedance and collective instabilities on the SNS Ring performance.
During the visit a plan was defined to integrate relevant algorithms in
the UAL environment.

# UAL 1.0: Off-line Simulation Environment: 

The Web documentation for the ORBIT module of UAL 1.0 environment has
been prepared. This documentation includes the description of Perl API
and C++ classes for parallel and non-parallel versions of the ORBIT
module. The new WEB-server Apache/1.3.14 was installed on the
Sun-Solaris system to allow testing new online UAL documentation.
Apache/1.3.14 allows easiest control than the existing WEB-server. A
DOC++, version 3.2, documentation system for C/C++ and Java
applications, has been installed onto Sun-Solaris system and Linux
cluster. This system enables us to generate WEB documentation on the
base of comments into a source code of applications.

Support and consultations were provided to the AP-group (Alexei Fedotov)
during the initial period of work with the parallel version of UAL 1.0
on the Linux cluster. A part of the supporting documentation was
revised.

The tune diagnostics package has been implemented in the UAL 1.0
environment. The package aims to facilitate the selection of the SNS
Ring working point

Worked with French colleagues planning to evaluate the UAL 1.0
simulation environment for the CONCERT (Combined Neutron Center for
European Research and Technology) project. During this visit we have
identified common tasks and approach for installing the UAL 1.0
environment on their computer system before the UAL 1.0 public release.

# SNS Ring Application Toolkit. 

N. Malitsky gave a talk on "SNS Ring Application Software Development"
for ORNL SNS scientists.

BNL worked with the ORNL Database team on the Optics Database schema.
During this visit we achieved agreement on tables for describing
sequences of accelerator devices. A small proof-of-principle experiment
was planned and will be implemented at ORNL and BNL over the next few
weeks

The Java-based Python ("Jython") was installed and tested.(Jython:
[http://www.jython.org](http://www.jython.org/) ). Jython is freely
available for both commercial and non-commercial use and is distributed
with source code. Jython is complementary Java and is especially suited
for the following tasks: embedded scripting and rapid application
development. Java programmers can add the Jython libraries to their
system to allow end users to write "middle-of-the-night" scripts.

# We have been preparing P&IDs and cabinet location drawings for the Ring Injection Dump in preparation for the 60% design review of utilities and controls in March. We have also worked on the specification for the Target shutter drive hydraulic system and how it will interface to the Target control system. We have not yet resolved whether the hydraulic drive vendor will provide a skid mounted control system or only the instruments and valves that will controlled by the SNS Integrated Control System (ICS). The decision will be determined by examining the capabilities of the vendors to provide the shutter drive controls. We have also been revising the instrument tabulation for the shutter drive system.

#  A contract for Target Systems cabinet fabrication and software development was received in March and is being evaluated. We are continuing preparation of wiring drawing for the PLC cabinets for the Target utilities as well as detailed P&Ids for the Target utilities.

**Significant Issues/Actions**

Most of the effort this month was in preparation for the 60% design
review for the Ring Injection Dump utilities and controls.

A decision to continue with the present Control Logix/EPICS architecture
was reached.

A restart workshop was held to plan for starting Title II design and
software development activities. All activities were stopped while the
architecture was being reviewed. The present Title I cost estimate was
reviewed and found to be adequate, agreement was reached on the
methodology for developing new deliverable dates and, decisions
concerning many design details were made. New schedule dates will be
developed in March.

Participated in the Conventional Facilities design reviews at San
Francisco to ensure that control system requirements are met. Prepared
and submitted an integrated communications \"backbone\" cable plan to
the AE. This will enable the AE to (a) size communications duct banks
and (b) design the cable plant required.

## **I. [WBS 1.9.9. Personnel Safety Systems ]{.underline}**

### **Technical Progress/Accomplishments**

A preliminary design has been developed for the target PPS. Design
features include:

-   "Chipmunk" radiation detectors will be used around the target
    monolith and the RTBT inside the building to detect abnormal
    radiation levels from beam operation. These detectors will be
    interlocked with the front end to shut off the beam if high
    radiation levels are detected.

-   Radiation detectors will be located in the basement, the galleries
    adjacent to the hot cell and in the high bay to detect radiation
    from activated materials. If abnormal radiation levels are detected,
    a local alarm is activated to alert personnel to evacuate the area.

-   Radiation levels from the Chipmunks and the radiation detectors will
    be sent to EPICS for display and archiving.

-   The personnel doors to the basement utility vault will be
    interlocked to the beam via the PPS. The access to the vault will be
    controlled by the PPS. The vault must be cleared of personnel before
    beam can be sent to the target.

-   The personnel entry doors to the transfer cell will be controlled by
    the PPS. These doors will be interlocked with the shield doors that
    isolate the transfer cell from the process cell and with radiation
    detectors located inside the transfer cell. The personnel doors
    cannot be opened unless the shield doors are closed and the
    radiation levels inside the transfer cell are acceptable.

Two vendors have responded to our inquiries for the production of new
Chipmunk IV radiation detectors for SNS. We plan to proceed with a
procurement for turn-key units. The vendor would be responsible for the
following activities:

-   Entry of existing schematics into a suitable CAD system

-   Redesign of selected components

-   Fabrication of two first article units for evaluation

-   Testing of the completed units

SNS and FermiLab would collaborate on a design review of the vendor s
drawings prior to fabrication of the first article units. The first
article units will be tested at FermiLab. After successful completion of
the first article effort, we would proceed with a procurement for
production units.

Sverdrup-Tullahoma (SvT) was supplied with preliminary information for
the PPS equipment required for the LINAC segment (this equipment is
required to support commissioning of the DTL). They are developing a
budgetary estimate based on this information and plan to complete the
estimate in early March.

A plan has been developed to generate the information needed to support
a title I design review of the Oxygen Deficiency Hazard (ODH) system for
the LINAC tunnel. The following information is required:

-   Hazard analysis for transient and steady state releases

-   Calculation that demonstrate the ventilation capacity of the He vent
    system for the LINAC tunnel (the capacity must meet or exceed the
    requirement from the hazard analysis)

-   A division document that states the safety functions and reliability
    level for the ODH system

-   A description of the ASD policy and procedures for ODH

-   A preliminary design, cost estimate and schedule

It has been suggested that the proposed NESHAPS stack monitoring system
may not be required for initial commissioning of the accelerator
systems. A meeting was held to develop a plan to determine stack
emissions during commissioning. We can use this data to determine when a
stack monitoring system would be required. The following plan has been
developed:

-   The beam losses for each commissioning phase will be documented

-   This data will be used to predict air and dust activation

-   Air and dust activation levels will be used to predict emission and
    dose levels

Several vendors have provided informal estimates on providing the PPS
PLC equipment for the LINAC segment (the first segment to be installed).
The estimates are in line with the CEDB. We plan to proceed to develop a
statement of work for the design, fabrication and testing for PLC
equipment for the LINAC segment. The vendor would perform the design for
the entire LINAC segment but would initially on fabricate the equipment
required for phase I (see item 2).

Detail design has begun on the PPS equipment required for phase I. Phase
I will provide access control for the LINAC tunnel from the front end to
the temporary shield wall located at the beginning of the SRF section of
the tunnel. A temporary gate will be installed downstream from the
shield wall to control access to the operational section of the LINAC
tunnel. The PPS will be operated from the front end control room. PPS
interfaces will be provided for the power supplies and RF systems
associated with the warm LINAC.

A subcontract technician has been brought on board to assist the PPS
staff. He will be responsible for fabricating the PPS PLC development
system, setting up the PPS section of the new control lab located at 701
Scarboro and assisting in the development of prototype PPS hardware. A
new door will be installed in the lab (to connect the lab to the
software development area). This door will be set up with PPS devices
similar to those planned for the PPS entrance doors to demonstrate PPS
design features.

A preliminary design has been developed for the PPS PLC development
system. The PLC equipment has been ordered and received.

A proposed design has been developed for the PPS controls of the primary
shutters in the target building. A series of key locks will be provided
in the Target basement control room. The locks will enable the operator
to close and secure the shutter in the closed position. This feature
would be used for example when neutron beam line shielding required
maintenance.

### **Significant Issues/Actions**

No significant issues this month

### **Variance Analysis (Cumulative To-date) (\$k)**

**[BCWS BCWP ACWP]{.underline} [SV %]{.underline} C[V %]{.underline}**

\$475.3K \$253.2K \$253.0K (\$122.1K) (47%) (\$0.2K) (0%)

1.  **Problem Statement:**

This variance is primarily due the FY00 variance described in Section I.
Although FY01 work is proceeding nearly as planned, it is beginning to
fall behind schedule due to CF design information arriving late.

2.  **Potential Project Impact:**

No project impact is expected. FY01 work is planned such that work not
completed in FY00 will be caught up by the end of FY01.

3.  **Corrective Actions:**

No corrective action is needed. The FY00 variance will be corrected as
stated in Section I.

##### WBS 1.9.10 Cryogenics Controls

### **Technical Progress/Accomplishments**

WBS 1.9.10

The cryo control development system hardware has been received and
connected to the development network. The EPICS drivers for the Highland
Technology Silicon Diode module and the LVDT module were updated to meet
SNS requirements. Testing of the EPICS driver software was started.

A development database with PLC and IOC tags was created to allow
testing of communication between the PLC and EPICS. Hardware was
installed to provide a test platform for the EPICS PID control loops
that use PLC inputs and outputs. A motor operated valve actuator (on
loan from JLab) was connected to the system to allow more realistic
testing of valve operations and position read back from the LVDT.

A preliminary layout of the PLC inputs and outputs for control of the
warm compressor and gas management system was completed. The design of
the layout of the warm compressor control racks was started.

A cost estimate for the connection of the "orphan" signals to the
control system was produced. These signals involve various parameters
associated with the superconducting cryomodules. Most are associated
with the RF systems. When the responsibility for the various subsystems
was distributed to the partner laboratories, there was not a clear
understanding of the boundaries of the work. Thus the orphan signals
were not included in the cost estimates for any of the subsystems. The
responsibility for each signal has now been defined. The cost estimate
for this work will be incorporated in a PCR prior to the end of March.

A preliminary layout of the PLC inputs and outputs for control of the
warm compressor and gas management system was completed.

A fully-prototypical and functioning PID control loop has been
implemented in the Cryo Control Development System. The PID loop is used
to control the temperature of a heater. The system includes an EPICS
operator interface screen (Created in EDM, the SNS standard screen
editor), an EPICS IOC with a MVME 2100 power PC, an Allen-Bradley
ControlLogix PLC, an Allen-Bradley PanelView Local operator interface
terminal, and a Remote/Local switch panel. The heater and temperature
sensor are connected to PLC inputs and outputs. The PLC and EPICS IOC
communicate via the SNS Standard EtherIP communication driver. The EPICS
cpid record is used for the PID loop. The PID loop runs in the IOC and
controls the heater when the Remote/Local switch is in the "Remote"
mode. The PID setpoint and tuning parameters may be adjusted using the
EPICS operator interface screen. When the switch is in the "Local" mode,
the user may use the PanelView terminal to set the PLC output to the
heater to any desired value (0 to 100% output). This is a significant
achievement for the Integrated Control System Development. It is the
first end-to-end implementation of a control loop utilizing the standard
ICS hardware, software, and operator interface screens.
