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

Spring Slice Test: where are we? TF/SP details, see Dan’s 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
CERN -- June 18, 2005 Endcap Muon Meeting / CMS Week
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.

CSC Timing
“Synchronization is pretty hard”[from J. Hauser’s 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
CERN -- June 18, 2005 Endcap Muon Meeting / CMS Week
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 Dan’s presentation
Last week, we saw the first L1As travel through our systems … Albeit at very low rate. But, this is an important step!
CERN -- June 18, 2005 Endcap Muon Meeting / CMS Week
17
CSC Timing (III)
Next steps L1A timing at CFEBs Adjust various timing windows
See Jay Hauser’s FNAL presentation
Update TMBtiming class will eventually contain all timing methods
Create detailed documentation CMS Internal Note on EMu timing

Calibration & Local DAQ
Calibration See Alex’s 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
CERN -- June 18, 2005 Endcap Muon Meeting / CMS Week

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

What’s 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

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
