Run Configuration

Summary

The PMT HV replacement and zig zag noise studies are beginning on the 24th, with commissioning continuing to the 25th. During daylight hours in this time we will have frequent expert accesses to the pit and will be taking intermittent zig-zag noise runs (config 633 while PMTs are off). Outside active works periods, shifters should take 5-minute noise runs once every two hours.

Notes on current operations:

  • We've been getting dewpoint alarms. The alarm limits are set more conservative than the cryo system's heater control. Therefore this is only a problem if the alarms persist for more than 30 minutes.
  • Similarly, the ZMON has been throwing frequent alarms. The relevant expert has been informed and investigations are ongoing.
  • While Jose is transferring SN data (he'll notify via the gchat), some seb*_memfree alarms may occur intermittently.
  • CRT Crate Rails alarms (uB_CrateRails_CRTUtil*) can be ignored until this line is removed from the run plan.

Additional Shifter Requirements:

  • Please follow the Shift_turnover procedures
  • At the end of your shift, please post a plot of the last 8 hours of variable: uB_Cryo_IFIX_1_0/PT102
  • During access to the detector:
    • Please fill out a Beginning of Detector Access and End of Detector Access Form.
    • If the "keytree" alarm occurs, and the persons accessing the platform have not called the shifter first, then call LArTF to find out who is accessing the detector. If no one answers, call the runco.
    • Detector platform access must be cleared by runcos.
    • At the end of detector access, please acknowledge the keybank incomplete alarm.

In Case of Cryo Alarms

All the cryo related alarms from either iFix or slow controls should be documented by shifters in ECL with the alarm variable names.

If a shifter does not receive a call within 15 minutes of seeing a MAJOR cryo alarm:
