DAQ

How to taking Data

Start Coda

  • How to run DAQ
    • From a terminal login as "adaq2" machine (do "ssh adaq@adaq2" without the quotes)
    • Password is available on the white board
    • After login to adaq2, type "startcoda" to bring up the runcontrol GUI
    • The default configuration is "coincidence", if it is not loaded you can choose it from the menu "configurations->Cool", select "coincidence"
    • Click "Platform->connect"
    • Click on "Download" button
    • Click on "Start (>>)" button, and acknowledge "start-of-run" pop-up window
    • To end a run click on "End" button
  • How to kill coda processes
    • At the terminal of adaq2, type "kcoda"


  • How to setup the Prescale
    • We just use PrescaleR for Ar experiment.
 login as "adaq" on "adaq2" machine
       type "prescaleR &" to open the GUI
       set desired prescale factors and click "Save" and Exit

Replay data

    • From a terminal login as aonl machine ( do "ssh a-onl" without the quotes)
    • Password is available on the white board
    • After login to a-onl, type gotritium, then Type
      analyzer
      .x replay_coinc.C
      runnumber (You can see the run number from CODA GUI)

Online GUI

(Last updated: February 15th 2017)

Once the run has been replayed (see instructions above), login to aonl1, aonl2, aonl3, or aonl4 as user a-onl (password on the white board) and do 

$ gotritium
[] onlineLHRS
[] onlineRHRS

The output files are stored under adaq1/data1/Ar40_[run number].root

Shift Workers

Counting house: 5501 & 5507 | Run coordinator: 876-1787 | MCC: 7046 & 7047 & 7048 | Crew chief: 7045 | Guard house: 8522

Your Responsibilities

Before the start of your shift: read, understand and sign the safety documentation of the experiments.

Shift Leader

  • Communicate clearly and effectively with shift crews and MCC (7047), and log any status information to the HALOG
  • Consult the daily run plans and communicate with [ run coordinator] whenever problems happen that cannot be solved by shift workers.
  • Maintain data taking quality and an efficient use of beam time.
  • Follow the directives in the COO
  • Log the following in a shift summary in the HALOG:
    • run list (describing the goal of this run: eg production on LH2, BMC calibration...) and report main statistic numbers
    • any major events, including accesses

Target Operator

  • Assist the shift leader and third person with their duties

Third person

  • Start and stop the DAQ. Record the purpose for every single run in the "Run list" binders. Read this to create more blank forms.
  • Online replay of all production runs (twice), as described in [online data analysis instructions]. First replay the first 50 k events, check online plots (see next bullet), then run a full replay.
  • Compare replay histograms with the sample ones and report to shift leader any unexplained differences. Halog them.


  • The shift leader or TO can help.

Slow control

How to bring up HAC control window (Hall A Tools), Monticello and JTabs

We like to run this display on is hacsbc2. The monitor is located in the Hall A Counting House in rack CH01A02, just below the NMR dipole oscilloscopes. Click here to see the screen.

If the display is not here: log onto the a-onl or the adaq accounts:

  • Hall A Tools: 'hlamain'
  • JTabs: 'jtabs'
  • Monticello" 'monticello'

JTabs is the newest version of the accelerator tools (it replaces monticello) and has some overlap witht he old EDM monticello and hlamain GUIs. It is most likely to be up to date and working, but maybe missing some items from the EDM tools. [Original halog with nice pictures

High Voltage controls (updated: 03/15, K.Park)

LHRS/RHRS : High Voltage controls

Login as "adev" on the "adaql1" or "adaql2" computers. (since I have added voice alarm for LEFT, RIGHT HRS and Compton HV, please note that command is different !)

cd ~adev/slowc

To run the Left HRS alone: ./hvsL LEFT

To run the Right HRS alone: ./hvsR RIGHT

To run the beamline (Compton) crate: ./hvsC BEAMLINE

The following instructions can be used for running the GUI using the vnc server How to open high voltage GUI. This is not how we want to run routinely.

[HV for experts]

cd ..

HRS HV alarm

If you hear about Left/Right HV alarm (either Red flashing rectangular box on screen .OR. Voice), please look at either LeftHRS or RightHRS HV GUI which are running on "adev" on the "adaql1" or "adaql2"

    • make sure "beepServer" is running on hapc3...If you are not sure run "/home/adaq/beep/start_beepserver"
