Information on EMMA DAQ

General info

EMMA DAQ computers

  • midemma01 - main daq computer in the ISAC2 CR#2 (TIGRESS)
  • midemma02 - terminal in ISAC2 on the table next to the EMMA platform
  • lxemma01 -EMMA VME processor (in the VME crate on the EMMA platform)

Storage:

  • 10TB ZFS volume on midemma01 mounted on the ISAC cluster machines as /emma/data1/emma

DAQ instructions

To start the DAQ:

  • login emma@midemma01
  • run "mhttpd -D"
  • open web page https://midemma01.triumf.ca
  • go to the Programs page, start all programs in order
  • go to the Status page, start a run, stop a run

To start the analyzer:

  • login emma@midemma01
  • cd online/ana
  • run ./emmana.exe -g -R8081
  • if a run is active, watch the histograms update every 15 seconds on the canvases
  • open web page: https://midemma01.triumf.ca/rootana/ (tailing slash is important!), watch the histograms on the web, click "monitoring" to enable periodic update.
  • to rebuild the analyzer, edit emma_module.cxx, then run "make". Use "make clean" to remove old object files, etc. Commit changes using "git commit ."

To change PID gates:

  • Open emma_module.h located in midemma01:~/packages/EMMA-Collaboration/emmana/include
  • modify values in lines 32 to 56. Specifically, variables called Total_E_low & Total_E_high, eICtot_min & eICtot_max, for the ICsum+Silicon and ICsum gates, respectively.
  • Save and stop/start rootana from the midas programs page.

FAQ

If the DAQ crashes here are some suggested diagnostics checks:

  • Check connection to feemma (VME crate): Type "ping lxemma01". If it does not respond then power cycle the VME crate at the focal plane.
  • Check the status of the mlogger program: Sometimes an interrupted connection can cause problems with the mlogger program, which will result in being unable to restart a new run. Type "ps aux | grep mlogger". If multiple mlogger programs are running then midemma01 will need to be restarted. You must perform a hard restart by holding down the power button.
  • Once both midemma01 and the VME crate are back up and running, follow the DAQ restart instructions listed above or type "start_daq.sh" in terminal.
