available Add chambers from other stations: ME+1 and ME+4

Spring Test Set-Up

At SX5, on or near YE+2 Peripheral Crate: based on std. VME crate. Using

a rev-1 6U backplane. Fully equipped with 9 production DMBs, 9 (old)

TMBs, pre-production MPC and CCB, and Dynatem Crate Controller

Connected to 6 CSCs, forming a 20° slice on ME+2 and ME+3

Fiber patch panel for DAQ/Trigger/TTC fibers Local control PC for Dynatem/iBoot

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 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


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


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!


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


18

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


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!

FRL crate(counting house)

Myrinet switch(counting house)


20

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


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
