Update threshold of alarm for N4 detector temperature

    Details

    • Sprint:
      preRun18August1

      Description

      ics_alertsActor uses pfs_instdata 1.7.48 for which the n2/n3 h4 detector temperature was adjusted to 101K (note; the original set temperature is 100K).  It was in order to control the detector temperature more easily when SCR room temperature is higher. After it, when n4 was installed in June, n4 detector was set to 101K although alerts was not adjusted. We may have the same issue for n1, which was recently installed.

      So, I think we should either (1) make a new tag-version with all n detector was set to 101K, or (2) change detector temperature to100K. (or do both)

          I agree with aiming for 101K on all. n2 is the difficult one, where the H4 heater is as low as we want to run it and the ASIC heater is being run quite high in order to try to keep the thing alive:

          Thank you for the comments. So can we go with 101K for all detectors?
