Plans for the 2004 CSC Beam Test

• Darin Acosta, Jay Roberts

2
Beam Test Goals
Shown at January EMU meeting

• Base goal
• Set up pre-production system and repeat prior
  tests using 25 ns structured beam
• New CCB design
• Additional goals
• Test TMB2004 with RAT
• Use new DDUDCC (FED) developed by OSU
• Use fully functional Track-Finder system
  (self-triggering)
• Use fully functional XDAQ-based event builder and
  run control
• Use new crate controller developed by OSU
• Add an ME1/2 chamber in order to have 3-chamber
  test (for SP)
• Swap ME1/1 in for ME1/2
• Mount an endcap RPC on ME1/2, connect Link board
  to RAT, record RPC data in TMB
• Add a small block of iron absorber between
  (15x15x30 cm?) to validate OSCAR/ORCA simulation

Test Beam Schedule
4
May/June Beam Test Schedule

• Two periods
• Asynchronous beam May 18 ? June 1
• CSC only at X5A for May 18 ? May 25
• CSC Tracker at X5A for May 26 ? June 1
• Synchronous beam June 7 ? 14
• CSC Tracker at X5A
• Muon studies with absorber best done during first
  week
• Well need a stand to move it in and out of beam
• Integrate new chambers during first period as
  well
• Electronics tests have priority during second
  period

5
2003 CSC Beam Test _at_ X5A
?/?
Two support stands constructed and available

• Tested two ME n/2 chambers in June and September
• Demonstrated successful operation of electronics
  in a synchronous 25 ns beam, including
  synchronous transmission through the optical
  trigger links to the Track-Finder

6
Possible 3-Chamber Configuration

• ME1/2 ME2/2 ME3/2
• Adds ME1/2 to previous beam test configuration
• Requires 1 new stand
• Could flip ME3/2 with respect to ME2/2 to emulate
  mounting on disks

7
Possible 3-Chamber Configuration

• ME1/1 ME3/2 ME4/2
• Adds ME1/1 to previous beam test configuration
• Requires 1 new stand
• Could run with ME1/2 as well for 4-chamber
  configuration?

8
Chamber Proposal

• Run with ME 1/1 ME 1/2 2 ? ME n/2
• Uses existing stands for two 10? chambers
• Assemble one new stand for ME 1/1 and one for ME
  1/2
• Stands need wheels for rotation and to roll out
  of beam
• Ability to change impact angle desirable
• Explore option of mounting an RPC to ME 1/2 for
  TMB connection
• Acquire peripheral crate electronics to run at
  least 3 chambers simultaneously
• Well need spares, so could we do all 4 chambers?
• Are two peripheral crates possible?
• Better from the point of view of the Track-Finder
• Need two MPCs, two VME crate controllers, two 9U
  crates
• Gas, HV, LV for all 4 chambers (including ME1/1)
• DAQ system to configure and collect data from all
  4

9
CSC Cosmic Ray Test Facility

• Currently testing the ME 2/1 ME n/2
  configuration at the UF cosmic-ray test stand
• Plan to start integration of software/hardware
  for TB2004 during the week of March 29

10
Status of New Electronics

• New CCB (Rice)
• Will be ready for testing in Florida by March 29
• Discrete logic implementation and TTCRq (QPLL)
  support
• TMB2004 (UCLA)
• Not yet available, expect 30 or more soon
• 4 ? TMB2003 will be made compatible with TMB2004
• Software changes for TMB2004 are expected to be
  small
• DDUDCC (Ohio State)
• Layout about completed
• Produced (tested?) by end of March
• New VME controller for peripheral crate (Ohio
  State)
• Also ready by end of March
• Track-Finder
• Sector Processor (UF) and Muon Sorter (Rice)
  tested and ready

11
Track-Finder Self-Trigger

• The Sector Processor has been fully tested since
  last beam test
• Track-finding is now possible
• Alignment offsets to wiregroup data will be added
  to emulate muons coming from collision point in
  beam test
• Full readout of inputs and outputs for tagging
  mode
• A Level-1 Accept signal will be generated based
  on the presence of a track
• Goes onto bussed backplane to CCB, then out
  front-panel
• Can be used to self-trigger the CSC system

12
Slow Control Monitoring

• Would be desirable to test DCS prototype during
  beam test and monitor some quantities (LV,
  temp,)
• We ran half-blind last year
• R.Clare thinks this should be possible
• Track-Finder will have LCT and L1 Track counters,
  as well as link error counters
• At the very least, these will be periodically
  read out and stored in a separate file for rate
  measurements
• We should think about having histograms produced
  in near real-time to judge quality of data

13
Manpower Preparations

• Institutes contributing electronics or chambers
  must have at least one expert available at CERN
  during tests
• Chambers should be moved late April or early May
• CERN FAST site Dubna
• Florida plans
• In addition to Levchenko and ISR team, several
  physicists to arrive beginning May 6
• Engineers arrive before 25 ns run
• Rice plans
• Several physicists to arrive beginning early May,
  engineer by 25 ns run
• Dubna
• Physicists and technician available
• Others ?

14
September/October Beam Test?

• Goals are ambitious for June!
• Use September test beam cycle to finish anything
  not accomplished in June?
• Move to H2?
• Could effectively have a slice test with HCAL,
  ME1/1, and DT
• We use a similar Run Control and DAQ system
  already
• ME1/1 wants to participate, but that implies
  already we are involved! (peripheral crate,
  software)
• Logistics and visa issues?
• HCAL/DT test goals already oversubscribed?
• First beam test with DT Track-Finder
• CSC manpower burn-out?
• Anyway, this years test beams will be the last
  for several years
