Run plan
See the daily plan in Run Coordination Meetings:Spring2023 and also the counting house whiteboard
Shift duties
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.
Screenshot tool
"Alt L" brings up the screenshot tool for making E-log entries
FCAL Base lockup
If FCAL HV bases lose communication and stop providing high voltage, refer to https://halldweb.jlab.org/hdops/wiki/index.php/Forward_Calorimeter_Shift#FCAL_Base_lockup
CDC Weather alarm
Alternative barometric pressure measurement in EPICS & how to use it: https://logbooks.jlab.org/entry/4117271
The measurement can be seen with LivePlot, B_SYS_WEATHER_SF_L3_Press .
A pressure difference of 0.4 in B_SYS_WEATHER_SF_L3_Press would be equivalent to a pressure difference of 0.1 kPa in Hall D's PV RESET:i:GasPanelBarPress1. That's the criterion for starting a new run.
( 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
The alarm has been disabled, see logbook entries 4114344, 4114307 )
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.
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).
