INTRODUCTION

This proposal requests beam time at Fermilab during the 2003-04 Meson
Test Run to test prototype silicon pixel detectors for the US-CMS
forward pixel detector. The discovery of the Higgs particles at the LHC
may depend on the identification of secondary vertices. This would be
impossible with a Si-strip tracker with its inner layer at 20 cm from
the beam line, such as the one for CMS. Pixel detectors starting at 4 cm
from the beam line will identify secondary vertices. This project is
funded through the US-CMS Project and through DOE and NSF Base Support.
Participating institutions are FermiLab, Johns Hopkins U., Northwestern
U., Purdue U., U. of C. Davis, U. of Mississippi, and Rutgers U.. This
effort has recently successfully tested prototype readout chips and
measured the electrical properties of pixel sensors. The bump bonding of
these components is in progress at UCD and with two vendors (MCNC and
IZM). We anticipate having bump bonded devices within weeks and we will
then proceed to test them with radioactive sources and laser beams. The
testing must then continue in a beam. The two main goals are to measure
the charge collection of the pixel detectors and their position
resolution, before and after irradiation. We expect the charge
collection to be high and consequently will proceed with the pre-
production submission of the sensors. The silicon telescope needed to
define the particle's trajectory with its DAQ will be supplied by the
group from Rutgers. Rutgers and Purdue have a proposal (T932-mou.doc) to
test diamond detectors in the same beam line.

Above are pictures of VHDIs with readout chips that we have recently
tested in the lab. Similar units with sensors read out by multiple ROCs
will be tested in the beam. Below we detail what we expect to accomplish
in the beam tests of the US-CMS pixel detectors as well as what
resources are required.

This is a memorandum of understanding between the Fermi National
Accelerator Laboratory and the US-CMS Pixel group. This test beam effort
will use the silicon telescope built by our colleagues from Rutgers and
utilized in test beam request T932. The same group will also supply the
necessary readout electronics for the pixel detectors. This electronics
exists, and it is presently being used at Rutgers, Fnal and soon at
Purdue.

The memorandum is intended solely for the purpose of providing a budget
estimate and a work allocation for Fermilab, the funding agencies, and
the participating institutions. It reflects an arrangement that is
currently satisfactory to the parties. It is recognized however, that
changing circumstances of the evolving research program will necessitate
revisions. The parties agree to negotiate amendments to this memorandum
which will reflect such required adjustments.

**II. EXPERIMENTAL AREA, BEAMS AND SCHEDULE CONSIDERATIONS**

1.  LOCATION

    1.  The experiment is to take place in the MTEST beam line and
        located in the area designated MT6-A2. In addition, the alcove
        control room to the east of the MTEST line will be used to house
        electronics (up to two 19" racks of electronics)

    2.  Additional work space will be needed in this control room,
        equivalent to at most two 6'x3' tables. This space will be used
        for computing and general work space.

2.  BEAM

    2.  The tests will use slow resonantly-extracted, Main Injector
        proton beam focused onto the MTest target. The tests require a
        beam of untagged, charged particles of energy approximately 80
        GeV.

    3.  Intensity: Variable, in the range of 1-10 KHz in an area of 1
        square cm. With the current beam line design this is expected to
        require up to 2 x 10^10^ primary protons per second.

    4.  We can make good use of the planned initial beam to MTEST.
        Currently this is envisioned to be a 1 sec spill per 60 sec
        supercycle. We anticipate some parasitic running during the test
        beams outlined in T927 (BTeV pixel test beam, located at
        MT6-A1). We would like to be informed of any accesses.

```{=html}
<!-- -->
```
2.  SETUP

    2.  At least one full day of access to the experimental area will be
        needed to set up the pixel test stand. This includes not only
        the silicon telescope planes and mechanical apparatus, but also
        the cable work. At least one additional day will be needed to
        install and debug the DAQ and NIM logic associated with the
        trigger. This would require only sporadic access.

    3.  Cabling to the counting room is significant. We have allowed one
        day of setup time. An outline of our cable needs between
        counting house and MT6-A2 include:

-   Strip sensors (3 cond. for power, 20 cond. ribbon, 6 RG58 BNC coax)

-   Pixel sensors (3 cond. for power, 60 cond. ribbon, 16 RG58 BNC coax)

-   Trigger scintillators (5 RG59 SHV for voltage, 38 RG58 BNC coax)

-   Power, Ethernet, DAQ interconnection cables (in counting house)

    2.  The time needed to switch setup between T932 and the US-CMS
        Pixel is about four hours with one hour of access time.

3.  SCHEDULE

    2.  We are requesting a few days of setup time followed by three
        weeks of regular data taking. Each run will consist of a few
        hours of measurements, and we will take data with about 8
        devices and possibly at several angles of incidence to the beam
        for each. Upon changing to a new device under test or a new
        angle of incidence, access to the experimental area will be
        needed for a brief period (1 hour to replace detector and 15 min
        to change angle).

# **VI. SPECIAL CONSIDERATIONS**

6.1 The responsibilities of the L2-Manager of the US-CMS Pixel group and
procedures to be followed by experimenters are found in the Fermilab
publication \"Procedures for Experimenters\" (PFX). The Physicist in
charge agrees to those responsibilities and to follow the described
procedures.

6.2 To carry out the experiment a number of Environmental, Safety and
Health (ES&H) reviews are necessary. This includes creating a Partial
Operational Readiness Clearance document in conjunction with the
standing Particle Physics Division committee. The L2-Manager of the
US-CMS Pixel group will follow those procedures in a timely manner, as
well as any other requirements put forth by the division's safety
officer.

6.3 The L2-Manager of the US-CMS Pixel group will ensure that at least
one person is present at the Meson Test Beam Facility whenever beam is
delivered and that this person is knowledgeable about the experiment's
hazards.

6.4 All regulations concerning radioactive sources will be followed. No
radioactive sources will be carried onto the site or moved without the
approval of the Fermilab ES&H section.

6.5 All items in the Fermilab Policy on Computing will be followed by
experimenters.

6.6 The L2-Manager of the US-CMS Pixel group will undertake to ensure
that no PREP and computing equipment be transferred from the experiment
to another use except with the approval of and through the mechanism
provided by the Computing Division management. They also undertake to
ensure that no modifications of PREP equipment take place without the
knowledge and consent of the Computing Division management.

6.7 Each institution will be responsible for maintaining and repairing
both the electronics and the computing hardware supplied by them for the
experiment. Any items for which the experiment requests that Fermilab
performs maintenance and repair should appear explicitly in this
agreement.

6.8 If the experiment brings to Fermilab on-line data acquisition or
data communications equipment to be integrated with Fermilab owned
equipment, early consultation with the Computing Division is advised.

6.9 At the completion of the experiment:

6.9.1 The L2-Manager of the US-CMS Pixel group is responsible for the
return of all PREP equipment, Computing equipment and non-PREP data
acquisition electronics. If the return is not completed after a period
of one year after the end of running the L2-Manager of the US-CMS Pixel
group will be required to furnish, in writing, an explanation for any
non-return.

6.9.2 The experimenters agree to remove their experimental equipment as
the Laboratory requests them to. They agree to remove it expeditiously
and in compliance with all ES&H requirements, including those related to
transportation. All the expenses and personnel for the removal will be
borne by the experimenters.

6.9.3 The experimenters will assist the Fermilab Divisions and Sections
with the disposition of any articles left in the offices they occupied,
including computer printout and magnetic tapes.

6.9.4 An experimenter will report on the test beam effort at a Fermilab
All Experimenters Meeting.
