> **1. INTRODUCTION**
>
> This Memorandum of Understanding applies to the use of the FNAL Meson
> Test Beam Facility to study the performance of several LHCb silicon
> vertex detectors. The tests will be carried out as a collaborative
> effort of CERN, Glasgow, Liverpool, and Syracuse Universities.
>
> The Vertex Locator (VELO) of the LHCb detector uses short silicon
> strips in a unique geometry that features strips at constant radial
> distance from the beam line and strips at almost constant azimuthal
> angle. The Silicon detectors in use at LHCb are implemented with n
> strips on n substrates. Prototype replacement sensors, however, have
> been produced using n strips on p substrates. The new processing
> scheme offers the prospect of producing significantly lower cost
> detectors for future projects and possibly better performance
> especially of irradiated sensors.
>
> We wish to compare the performance of the n-on-n and n-on-p detectors
> for irradiated and non-irradiated sensors. To do so, the experimenters
> plan to use the pixel telescope being constructed in the MTest
> facility. In particular, the experimenters are planning to study the
> efficiency of the irradiated and unirradiated devices and the spatial
> resolution as a function of the track incident angle. They vary over
> the sensor area due to the unusual geometry. The experimenters will
> also change the incident angle of the beam by moving the sensors, to
> investigate how the resolution varies with angle. Besides VELO
> sensors, some n-on-p sensors are available from the RD50 collaboration
> at CERN. Many physicists participating in this test beam are members
> of RD50.
>
> This memorandum is intended solely for the purpose of providing a work
> allocation for Fermi National Accelerator Laboratory and the
> participating universities and institutions. It reflects an
> arrangement that is currently satisfactory to the parties involved. It
> is recognized, however, that changing circumstances of the evolving
> research program may necessitate revisions. The parties agree to
> negotiate amendments to this memorandum to reflect such revisions.

3\. EXPERIMENTAL AREA, BEAMS AND SCHEDULE CONSIDERATIONS

1.  3.1 LOCATION

    1.  The tests will take place in MT6-A1.

    2.  Lab space shall be provided for pre-testing the detectors and
        making repairs as necessary. This shall include two \~30"x72"
        work surfaces in a low dust environment equipped with ESD-safe
        surfaces and grounding and lights.

    3.  Office space including two desks and network connectivity will
        be provided for the duration of T-971.

> 3.2 BEAM

1.  Type of Beam Needed: 120 GeV proton beam

2.  Intensity Needed: 10-100k particles/ (4s spill)

> Beam Size Needed: \~ 10 cm**^2^**

3.  EXPERIMENTAL CONDITIONS

    1.  Provision will be made for the devices under test (including the
        largest VELO sensors) to be rotated with respect to the beam
        direction.

    2.  The pixel telescope upgrade for the beam line is required. The
        experimenters can offer some manpower help in commissioning the
        telescope.

    3.  The test environment shall be humidity-controlled, preferably
        with the test devices in a dry nitrogen atmosphere.

    4.  There shall be refrigeration capability so that the detectors
        can be operated at 10^o^ C, the operating temperature at LHCb.
        The LHCb modules dissipate approximately 20W each. Given the
        construction of the hybrids a cooling capacity of \~50W at 30C
        (temperature of the cooling interface) should be foreseen.

    5.  The experimenters will provide all the computers needed for DAQ
        and data analysis and disks for data storage.

    6.  Fermilab will provide 250 Gbytes of space on a managed disk
        server that the experimenters will use for short-term backup of
        test beam data.

```
4.  ELECTRONICS:

> The system is read out through a custom DAQ system. An interface board
> will be used to route the data to an online computer connected to a
> Fermilab server via internet. The readout boards will be located near
> the detector in the hut. The detector themselves are run at up to
> \~300 V. No exposed HV parts will be present.
>
> 3.5 SCHEDULE:
>
> The time schedule is primarily dictated by the availability of the new
> pixel telescope in the test beam. As this is expected to be completed
> in the spring of 2008, the experimenters would envisage running their
> tests at that time. The experimenters are willing to arrive earlier
> than that to help commission the facility pixel telescope.
>
> The experimenters envisage a 3 weeks running time divided into three
> approximately equal phases:

1.  Setup and synchronization, where the devices under test are put into
    the text box at the nominal \"normal to the beam\" position, and the
    operating conditions are optimized and synchronization with
    scintillator trigger and pixel telescope is implemented.

2.  Data taking with VELO modules: it is envisaged to take data at 6
    angles and different VELO positions to investigate resolution and
    efficiency at various bias voltages for the full detector
    acceptance.

3.  Setup and test of RD50 strip detectors at a few beam angles.

4.  RESPONSIBILITIES BY INSTITUTION - NON FERMILAB

```{=html}
<!-- -->
```
1.  The personnel from Syracuse, Glasgow, Liverpool and CERN will set up
    equipment on the beam line under the Fermilab Particle Physics
    Division guidance and supervision, provide the DAQ and slow control
    systems, provide test beam coordination and funding for its
    personnel during the beam test.

```{=html}

```
5.  RESPONSIBILITIES BY INSTITUTION - FERMILAB

## 5.1 Fermilab Accelerator Division:

1.  Use of MTest beam as outlined in Section 3.

2.  Maintenance of all existing standard beam line elements (SWICs, loss
    monitors, etc) instrumentation, controls, clock distribution, and
    power supplies.

3.  Reasonable access to the experimenters' equipment in the test beam.

4.  The test beam energy and beam line elements will be under the
    control of the AD Operations Department Main Control Room (MCR).

5.  Position and focus of the beam on the experimental devices under
    test will be under control of MCR. Control of secondary devices that
    provide these functions will be delegated to the experimenters as
    long as it does not violate the Shielding Assessment or provide
    potential for significant equipment damage.

    5.2 Fermilab Particle Physics Division

> 5.2.1 The Fermilab Particle Physics Division will be responsible for
> coordinating overall activities in the MTest beam-line, including use
> of the user beam-line controls, readout of the beam-line detectors,
> and MTest gateway computer.

2.  PPD will maintain scintillation counters that are part of the Meson
    Test Beam Facility.

3.  PPD will provide on-call LINUX DAQ computing support during normal
    working hours.

4.  PPD will commission and maintain the Meson Test Beam Facility pixel
    telescope and assist in coordinating it with the experimenters DAQ.

5.  PPD personnel will modify the "pixel box" to allow it to be used for
    VELO testing as detailed in 3.3. It is estimated that 3 weeks of
    engineering will be required to design the required cooling systems
    including isolation of cold and warm sections of the pixel box.
    Approximately one week of designer effort and 4 weeks of technician
    time will be required for modifications to accommodate the VELO
    sensors. The M&S cost associated with the modifications and the
    cooling system is estimated to be \$20k.

6.  PPD will provide office and lab space as detailed in 3.1.

> 5.3 Fermilab Computing Division

1.  Ethernet and printer will be available in the counting house.

2.  Connection to beams control console and remote logging (ACNET)
    should be made available in the counting house.

7.  SPECIAL CONSIDERATIONS

7.1 The responsibilities of the PI of the Syracuse group and the
procedures to be followed by experimenters are found in the Fermilab
publication \"Procedures for Experimenters\":
(<http://www.fnal.gov/directorate/documents/index.html>). The Physicist
in charge agrees to those responsibilities and to follow the described
procedures.

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

7.3 The PI of the Syracuse 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.

7.4 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.

7.5 All items in the Fermilab Policy on Computing will be followed by
the experimenters. (<http://computing.fnal.gov/cd/policy/cpolicy.pdf>).

7.6 The PI of the Syracuse group will undertake to ensure that no PREP
or 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.

7.7 The SYRACUSE group 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.
