Taking cosmic data in the ESB and setting HV

  1. ssh into genl5 (computer in ESB), even if you are already on the machine (to make sure css loads correctly)
  2. Do not source coda_bcal_setup in /home/halld/bcal_test
  3. type 'css' to bring up the slow controls HV gui
    • If an error screen comes up try to the following:
      1. ps -ef | grep BCAL (to get localhost id)
      2. telnet localhost 20000 (or other from ps command)
      3. ctl-x (reboots server)
      4. ctl-] (escapes to telnet prompt)
  4. For cosmics in ESB use 'halld' account instead of 'halldrun' and use 'genl5' computer instead of 'clonusr2'. 'halldtrg3' is still used. Otherwise, follow instructions below
  5. When css looses communication, reset the crate as follows
    • Turn power off
    • Unplug ethernet (blue) cable
    • Turn power back on
    • Plug ethernet cable back in

Instructions for 2012 Beam Test in Hall B

  1. Launch database daemon
    • login to clonusr2.jlab.org under halldrun
    • start msqld by typing 'msqld' ( be sure that only one msqld is running)
  2. Launch Afec-1.4 platform
    • login to clonusr2.jlab.org under halldrun
    • type 'platform'
  3. Start event builder
    • login to clonusr2.jlab.org under halldrun
    • coda_eb_rc3 -i -s simple -n EB3 -t CDEB
  4. Launch coda_roc on the Linux controller
    • login to halldtrg3.jlab.org under halldrun
    • coda_roc_rc3 -i -s simple -n TROC3 -t ROC
    • Note: If TDCs are empty, reboot crate: On clasrun@clon10 >roc_reboot halldtrg3
  5. Launch Run Control GUI
    • login to clonusr2.jlab.org under halldrun
    • type 'rcgui'
    Select 'Sessions -> simple'
    Select 'Configurations -> Cool -> bcal' (see top menu)
    Press buttons: Configure, Download, Prestart, Go (you start the run)

Check data

  • To check the data do the following
  1. In the /home/halld/bcal_test/data directory type
    • emacs raw_check2.C &
    • Change the run number on the line with Int_t runno=###;
    • Save the change using the down arrow below the 'Buffers' command
  • To look at the data, in the /home/halld/bcal_test/data directory type
  1. bcal_beam simple_855.evt.0 using the correct run number
  2. root
  3. root [0] .x raw_check2.C (can use the up arrow)
  4. hit return twice for the data to be displayed
  5. .q (to exit root)



Store data on tape

  • To store data on tape just copy files on clonusr2 to
/w/stage/output/clas/test
To retrieve files, go to ifarms ( ssh ifarml64 ). You can see files using
ls /mss/clas/test/bcal*
  • To retrieve a file from the tape use
jget /mss/clas/test/file_name .
