Spring Slice Test Scope Goals

• One of the stepping stones towards the Cosmic
  Challenge
• 2nd half of April
• Announced at our previous EMu Meeting
• Infrastructure ready (fibers, counting house,
  etc.)
• except for rack cooling in the Counting House
• Experts invited
• Connect and time-in 6 CSCs
• Self-trigger on cosmics using TF
• Provide data to Central DAQ

13
Spring Slice Test where are we?

• TF/SP details, see Dans presentation
• Updated/verified firmware on all CFEBs and DMBs
• Jason
• Updated firmware on all TMBs and ALCTs
• Yuri/FG
• ALCT firmware is now uploaded via the TMB, using
  the PeripheralCrate library
• Documentation available at our website
• ALCT mirrored firmware on ME3 chambers,
  specially updated and tested for Slice Test by
  Alex M.
• Fully loaded rev.1 peripheral backplane resulted
  in communication problems with the ALCTs
• Temporary removing 6 out of 9 TMB/DMB pairs
  alleviates the problem
• Reintroduce after first CSCs are completely set-up

14
Spring Slice Test where are we? (II)

• TTC electronics
• Both TMB and SP timing tests showed intermittent
  response to B-Go commands
• Initially observed single-bit shifts of CCB
  commands in the TTC B-channel, where double-bit
  shifts were expected
• Occasional single and double errors at the TTCrq
• Traced back to incorrect A and B-channel timing
  between TTCvi and TTCvx (thanks to Jan T.)
• First stab at internal Slice Test note on TTC
  configuration for future reference.
• Available at our website

15
CSC Timing

• Synchronization is pretty hard
• from J. Hausers summary at the FNAL EMu
  Meeting
• Conceptual Manual exists
• Recently updated powerpoint presentation
• First step
• adjust clock phases between TMB and CFEB
• Adjust TX and RX clock phases between TMB and
  ALCT
• Requirements
• Up-to-date ALCT configuration software
• tmbtiming.exe command line package which sets up
  and executes automated timing procedures
• To be replaced by a dedicated TMBtiming class
• useable through the XDAQ interface
• Second Step already requires L1As in the system
• Will be provided by TF/SP

16
CSC Timing (II)

• First step is done for all 6 chambers
• Use DMB/CFEB pulser to find optimal TMB-CFEB
  clock phase
• Use ALCT test strip pulsing to find optimal
  TMB-ALCT tx/rx clock phases
• Second step requires L1As
• Generate ghost tracks and have the MPC send two
  muon candidates to the SP
• Work in progress See Dans presentation
• Last week, we saw the first L1As travel through
  our systems
• Albeit at very low rate.
• But, this is an important step!

17
CSC Timing (III)

• Next steps
• L1A timing at CFEBs
• Adjust various timing windows
• See Jay Hausers FNAL presentation
• Update TMBtiming class
• will eventually contain all timing methods
• Create detailed documentation
• CMS Internal Note on EMu timing

18
Calibration Local DAQ

• Calibration
• See Alexs presentation
• Uses DAQMB/CFEB pulser
• Triggered by TTC B-Go or CCB
• Adjusted DAV windows
• Part of the FAST site test suite that needs to be
  ported to the PeripheralCrate Library
• New CalibDAQ class available in TriDAS/emu
  repository
• Local DAQ
• Similar to Beam Tests DDU spy channel into
  emuslice02
• Used to retrieve Calibration data at the Slice
  Test
• And, is likely to be needed for all other FAST
  site tests
• DDUReadout/HardwareDDU classes to retrieve data
• HardwareDumper command-line, for testing
  purposes
• EmuRUI (preferred method) XDAQ-based, DQM hooks

19
EMu Central DAQ

• S-Link cable connectes DDU/DCC to FRL (CMS-DAQ)
• FRL connects us to a CMS DAQ column
  (RUI/RU/BU/FU)
• Successful first tests
• 1309 events recorded by FRL and local spy channel
• Important milestone for EMU and CMS-DAQ
• First CMS subsystem to provide data to DAQ!

EMu Central DAQ (II)

• After the first 1309 events, we ran a 100k
  single-chamber calibration run
• Event counts identical
• CRC checks agree
• Next,
• Very long run (this weekend)
• CRC verification
• Increase event size (this weekend)
• Add more chambers
• Variable event size
• Use cosmics data
• Pass data on to a simple DAQ column

Whats next?

• After Spring comes Summer Test
• Continue timing efforts
• Integrate trigger with Cosmic Challenge Local
  Trigger Control
• Introduce 2nd Peripheral Crate and separate ME2
  and ME3 chambers out. Use 2nd MPC feed to SP.
• Need more (old) TMBs
• Introduce OSU Crate Controllers
• XDAQv3 migration
• EMu Slice Test Workshop July 11 15 at CERN
• Discuss our Summer Plans
• I sent out to the EMu SliceTest mailing list a
  personal and likely incomplete list of tasks
  relevant to the Slice Test
• E.g. draft and discuss the CMS Internal Note on
  CSC timing

22
Summary

• With the Spring Test, the Slice Test is now well
  under way
• Many thanks to all who have helped and still do!
• 6 CSCs are hooked up and have been operational
  throughout ever since the Spring Test
• Fiber duct installation
• Timing of the chambers partially done
• Not as fast as we hoped, but
• this is a more complicated procedure than at
  the TBs
• Self-trigger no external trigger source
• EMu first CMS sub-detector to provide data to
  Central DAQ
• Summer Plans
• July Workshop at CERN
• Integrate with Cosmic Challenge LTC
