Run Configuration

Summary

For the weekend of the 9th to the 10th, the detector is completely OFF. Disregard the instructions below (you will not be able to take noise runs) and solely monitor for alarms. Please pay particular attention to cryo.

Currently, we are taking noise data with the detector with the following systems OFF:

  • TPC Cathode HV
  • Wire Bias
  • PMTs
  • Purity Monitor
  • Laser system

Outside active works periods (i.e. runcos/experts on the platform + in the control room), shifters should take 5-minute noise runs (config 633) once every two hours.

The RunCat is currently down, so you will be unable to do the usual RunCat checks until it is back up. Slow controls and IFIX alarms should still be monitored as per usual.

- Pip.

Run Control

Configuration Config ID Time [min]
Zig-Zag Noise Run Configuration 633 5
ASIC config to unmask noise on FT6 630 5
ASIC config to return FT6 to normal operation 631 5

Configs 630 and 631 are misnamed and will be deleted after this period of works is over. They are not to be used for the 5 minute noise runs; only recorded here for posterity when we want to come out of the zig-zag testing configuration.

Notes on current operations:

  • MiniBooNE is down until 9/18.
    • Do not fill out the miniboone checklist.
  • 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.
  • You may see major OnDetPower HIHI alarms from TPCPS_2_10_904 and 806. These are negative channels whose upper limits are set close to zero - with the wire bias off, small fluctuations in the readback around zero can put them into alarm. Feel free to acknowledge these when you see them; if they reappear it will be due to small fluctuations clearing the alarm state and then putting it back into alarm.

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:
