Short Term Run Plan
Contents
Current Experiment
Rare Eta Decay & GlueX II (with DIRC)
- Experiment number: E12-12-002 (use in BTA shift information)
- Proposal
- Spokesperson: C. A. Meyer
Notes
- All GlueX detectors (including DIRC)
- CDC Weather alarm, aka Alarm on HD:coda:cdc:p_diff, see https://logbooks.jlab.org/entry/4001862
- Stop run - Acknowledge alarm and document it - Start new run
Run conditions
Hall D counting room whiteboard
- Radiator: JD70-103 50 um diamond (4 orientations: 0, 90, 45, -45)
- Collimator: 5.0 mm
- TPOL converter: Be 75 um
- Runs are no more than 2 hours - see whiteboard for the production cycle
- Target: Liquid Hydrogen
DAQ config
- Setup: TBA
- Production: TBA
- (Raw mode: config TBA)
Run plan
See the daily plan in Run Coordination Meetings:Spring2023 and also the counting house whiteboard
Shift duties
GlueX Guidelines are at Shift_Guidelines_for_Shift_Leader and Guidelines_for_Remote_Worker_Shift
Run comments
Put information, eg "production ...nA <target>", 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.
List of production runs
- Include a separate list of the runs taken during the shift at the end of the shift leader summary
- Please include the following:
- run number, start & stop times, number of events, production/test/junk/any_other_comment
BTA sheet
- The BTA guidelines are at BTA_guidelines.
After loading the EPICS values, you may change the values, eg round them up or down.- BANU values should be reflected in the PCC (or UED) value (else the aftermath doesnt work out for RC), put a comment for > 5minutes.
- UED: unplanned experiment down (hardware failure).
Strip Charts
- Log the strip charts of beam current and position, see Slow_Controls_Shift#MYA_Archiver
- on a gluon machine type LivePlot
- right-click on the screen and select "Load a Configuration"
- the configuration "beam_psc" provides the currently desired information
- right-click on the screen and select "Make Elog Entry", make sure you do not log to ELOG but to HDLOG.

Special instructions
Hall Delta
It's good practice to refer to our hall as Delta when talking to MCC, to make sure that there is no acoustic confusion between us and Hall B.

After beam restoration
- See Beam_Line_Detectors_Shift#Collimator_and_Radiators on how to move radiators and collimator
- check the radiation levels without radiator and then with the radiator
- see the whiteboard (bottom RHS corner of the RH board) - there are columns of values expected without and with the radiator
- retract the radiator
- collimator in blocking position
- ask MCC to do their harp scan
- our harp scans: follow the instructions in Beam_Line_Detectors_Shift#Radiator_Harp_Scan
rootspy
If you have to restart rootspy, Online_Monitoring_Shift#Routine_Operation, and it crashes, you might have to restart the monitoring process, find help at Online_Monitoring_Shift#Starting_and_stopping_the_Monitoring_System.
DAQ issues
Call the expert. In case they suggest that you restart the DAQ, find information at Data_Acquisition_Shift.
