Short Term Run Plan

Current Experiment

Measuring the Charged Pion Polarizability in the γγ -> π⁺π^- reaction

• Experiment number: E12-13-008 (use in BTA shift information)
• Proposal: PAC link

Notes

• ST: not installed
• CDC
  • one quadrant is OFF (crate CDC1)
  • Alarm on HD:coda:cdc:p_diff, barometric pressure has changed by 0.1 kPa or more since the start of the run,see https://logbooks.jlab.org/comment/38202#comment-38202

Run conditions

Hall D counting room white board

• Radiator JD70-103
• Collimator 3.4 mm
• TPOL converter 750 um

DAQ config

• setup hd_all.tsg_CPP
• production config FCAL_BCAL_PS.CPP_m9.conf

Sun, Jun 12, 2022, Early Riser

production runs with improved trigger

• Target status: Pb target IN
• beam current 60 nA
• runs are 2 hours

Shift leader

GlueX Guidelines are at Shift_Guidelines_for_Shift_Leader

run comment

Put information, eg "production 25 nA Pb", in the run comment window of the DAQ. This comment is needed for RCDB.

The run comment window should appear automatically after a run has been started. Enter the comment and SAVE, do not exit.

list of production runs

• Include a separate list of the runs taken during the shift at the end of the summary (for example, see https://logbooks.jlab.org/entry/3936066)

strip charts

• Log the strip charts of beam current and position, see Slow_Controls_Shift#MYA_Archiver
  • on a gluon machine type myaPlot
  • right-click on the blank space of the myaPlot screen and select "Clone in new LivePlot"
  • right-click on the screen and select "Load a Configuration"
  • the configuration "beam_conditions" provides the beam current and position information
  • right-click on the screen and select "Make Elog Entry", make sure you do not log to ELOG but to HDLOG.

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 >= 5 minutes must be reflected in the PCC value (else the aftermath doesnt work out for RC)
  • BANU values < 5 minutes may be set to 0
  • UED: unplanned experiment down (hardware failure)

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.

target status

• check camera west-cam.jlab.org, select Target view, if necessary
• look for yellow (small) flag as in https://halldweb.jlab.org/hdops/wiki/images/3/34/Lead_target.gif
• yellow flag visible: target IN
