    DIRC activities

    See DIRC logbook for details

  • Sat 29th : There was a failure in the power to the degasing pump panel. Since the SOB water level monitor is on the same panel, this caused SOB dump and SOB water level alarms. Jerry was able to restore the power and fix the problem; he also moved the degasing pump over to UPS power again, to relieve the load on the normal power.
  • Thu 3rd : Background monitoring plots have stopped updating - hardcoded 'End of Run 5'? Await Nicolas' return.
  • Thu 3rd : There is a bit of a funny smell in the DIRC gas rack. Jerry will investigate.
