1. Plans for the 2004 CSC Beam Test
Darin Acosta, Jay Roberts

2. Beam Test Goals Base goal: Additional 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 DDU+DCC (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

3. Test Beam Schedule
16 March 2004
CMS Week

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
We’ll 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 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
16 March 2004
CMS Week

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
16 March 2004
CMS Week

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?
16 March 2004
CMS Week

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
We’ll 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 MPC’s, 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
16 March 2004
CMS Week

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
16 March 2004
CMS Week

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
DDU+DCC (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
16 March 2004
CMS Week

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

CMS Week

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
16 March 2004
CMS Week

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 year’s test beams will be the last for several years
