Coordinate Detector

The Coordinate Detector (C-Det) is a passive PMT based detector used to measure the electron's vertical angle at a resolution of 1.2 mm. Using C-Det as a component of GEp, a proton form factor experiment, will also significantly reduce the proton track search region during experimentation.

DAQ computer is uvagem

Intel VME CPU is sbsvme1a

We have MPDs in slot 3,4,5,6 (v3.0 firmware with FIR)

Checkout of Bryan's MPD is in git/mpd , repository is located at /site/coda/contrib/devel/

Turning V1495 pulser on

 login on srcdaq as a-onl
 go in /home/a-onl/altera/10.1sp1/quartus/bin
 launch quartus
 open  /home/a-onl/Downloads/V1495/FIT
 open programmer
 load the firmware

Running MPD with CODA

 Login on triton
 Start CODA

If ROC is not started yet : on sbsvme1a type ,

 source coda_user_setup
 coda_roc_rc3.5 -name MPD11 -type ROC

In Run Control : select the MPD configuration and start a run

This section contains instructions for running the replay script with all detectors on a-onl@aonlX.

Instruction for shift crew

  • Login to a-onl@aonlX (X=1, 2, 3, 4)
  • once logged in, type gosbs => this takes you to the directory where the analysis should be done, and sets up the correct environment variables.
  • type ./run_gmn.sh runnum nevents with
    • runnum (integer) the run number you want to analyze;
    • nevents (long integer) the number of events you want to analyze.
  • note: in a very near future, we might even fix the number of events

Specific instructions for experts

Note: these instructions are likely to evolve in a very near future

  • Login to a-onl@aonlX (X=1, 2, 3, 4)
  • once logged in, type gosbs => this takes you to the directory where the analysis should be done, and sets up the correct environment variables.
  • open the analyzer by typing analyzer
  • once in the analyzer type .L replay_gmn.C+
  • type replay_gmn(runnum, nevents, firstevent, file_prefix, firstsplit, nsplits, pedestalmode) with:
    • runnum (integer) the run number you want to analyze;
    • nevents (long integer) the number of events you want to analyze.
    • firstevent (long integer) the event number from which you want to start the analysis;
    • file_prefix (char*)the prefix of the file you want to analyze;
    • firstsplit (integer) the split/segment number at which you want to start the analysis;
    • nsplits (integer) the number of splits/segments you want to analyze
    • pedestalmode (integer) turn pedestal mode on or off for the GEMs
