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

Run conditions

Hall D counting room white board

  • Radiator JD70-103
  • Collimator 3.4 mm
  • TPOL converter 750 um
  • Coherent edge (not yet)

DAQ config

  • setup: hd_all.tsg_CPP
  • production: config FCAL_BCAL_PS.CPP_m9.conf
  • (raw mode: config FCAL_BCAL_PS.CPP_m10.conf)

Run plan

Sun, Jun 12, 2022, Early Riser

commissioning runs with improved trigger

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

Shift duties

GlueX Guidelines are at Shift_Guidelines_for_Shift_Leader and Guidelines_for_Remote_Worker_Shift

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

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.

After beam restoration

Target status

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.

Timing problems

If there are any, please add sdobbs@jlab.org to the notifications in the logbook entry.

Example double timing peaks: https://logbooks.jlab.org/entry/3933110

Shoulders on timing peaks might be features and not problems: https://logbooks.jlab.org/entry/3933867
