Production running cycling through targets:
−
* All GlueX detectors, except DIRC
+
* '''JD80-212 80um''' diamond, '''200 nA''' beam current
−
* CCAL in use (4 m downstream FCAL to cover polar between 0.2 and 1 degree and measure Compton events in combination with FCAL)
+
** 800M events for '''0/90 deg''' and '''PARA''' setting
−
* CDC Weather alarm, aka Alarm on HD:coda:cdc:p_diff, see https://logbooks.jlab.org/entry/4001862
+
** 800M events for '''0/90 deg''' and '''PERP''' setting
−
** Stop run - Acknowledge alarm and document it - Start new run
+
** 800M events for '''45/135 deg''' and '''PARA''' setting
 +
** 800M events for '''45/135 deg''' and '''PERP''' setting
 +
* 400M events with '''4.5×10-4 Al 40um''' radiator (on goniometer!), '''300 nA''' beam current
 +
** Set '''new reference for amorphous radiator''' in CBREM GUI.
 +
* Runs should be no longer than 2 hours.
 +
* Keep the state of the production cycle on the whiteboard up-to-date.

* Radiator (Amorphous) 10 µm Al (1 x 10-4 RL)
+
* Put '''comments''' for each run in the window opened by the DAQ.
−
* Collimator 5 mm
+
** The comment should at least contain the following information "<radiator> <PARA/PERP>, <beam current>, LH2 target, <typical trigger rate>, <typical live time>, <issues if any>"
−
* TPOL converter Be 750 µm
+
** Example: "JD80-212 80um 45/135 PARA, 200nA, LH2 target, 81kHz, 93% live time"
 +
** Note: due to a software issue run comments may not show up in RCDB, but they are saved by the DAQ and will be later added to the RCDB entries.
 +
* Set a new '''amorphous reference''' in the CBREM GUI each time the amorphous radiator is used.
 +
* Be sure to hit the '''"PARA" or "PERP" button''' in the CBREM GUI when switching diamond targets. Otherwise the diamond alignment may be in an undefined state and the experiment may be flooded with low-energy photons.
 +
* Watch for '''locked-up FCAL HV bases''' towards the end of a run and clear them before starting a new run. See [https://halldweb.jlab.org/hdops/wiki/index.php/Forward_Calorimeter_Shift#FCAL_High_Voltage_channel_with_yellow_border].
 +
* Watch the '''DAQ lifetime''' when beam is on. Sometimes it drops to 0%. Just stopping and restarting the run fixes this issue in most cases.

Put information, eg "production 25 nA Pb", in the run comments window of the DAQ. The comments are needed for RCDB.
+
−
 
+
−
The run comments window should appear automatically after a run has been started. Enter comments and SAVE, do not exit. If the run comments window is visible, check first whether it is hiding eg on the upper workspcace. If it is not up, restart the DAQ before start of the next run.

Run Plan

Production running cycling through targets:

  • JD80-212 80um diamond, 200 nA beam current
    • 800M events for 0/90 deg and PARA setting
    • 800M events for 0/90 deg and PERP setting
    • 800M events for 45/135 deg and PARA setting
    • 800M events for 45/135 deg and PERP setting
  • 400M events with 4.5×10-4 Al 40um radiator (on goniometer!), 300 nA beam current
    • Set new reference for amorphous radiator in CBREM GUI.
  • Runs should be no longer than 2 hours.
  • Keep the state of the production cycle on the whiteboard up-to-date.

Special instructions

  • Put comments for each run in the window opened by the DAQ.
    • The comment should at least contain the following information "<radiator> <PARA/PERP>, <beam current>, LH2 target, <typical trigger rate>, <typical live time>, <issues if any>"
    • Example: "JD80-212 80um 45/135 PARA, 200nA, LH2 target, 81kHz, 93% live time"
    • Note: due to a software issue run comments may not show up in RCDB, but they are saved by the DAQ and will be later added to the RCDB entries.
  • Set a new amorphous reference in the CBREM GUI each time the amorphous radiator is used.
  • Be sure to hit the "PARA" or "PERP" button in the CBREM GUI when switching diamond targets. Otherwise the diamond alignment may be in an undefined state and the experiment may be flooded with low-energy photons.
  • Watch for locked-up FCAL HV bases towards the end of a run and clear them before starting a new run. See [1].
  • Watch the DAQ lifetime when beam is on. Sometimes it drops to 0%. Just stopping and restarting the run fixes this issue in most cases.
  • New hdops wiki feedback form is here please use this to report confusing or outdated wiki instruction pages.
