    See DIRC logbook for details
  • Friday 23rd : Matt replaced a water pump. Discovered that fan monitoring plots were not being updated properly; it seems the commissioners have failed to look at the dates on the x axis. The 'monthly' plots were showing April... Nicolas fixed the scripts. Lesson : Do not just look at the time development, also check what time the plots are for!
  • Monday 26th : To avoid problems while the UPS work was going on, Matt disabled the dump valve and put the degassing and vacuum pumps on house power. When the work ended, we found that the VME crate was not communicating with epics; we replaced the fan tray, and that fixed thsi problem. We also needed to reboot the GMB.
  • Wednesday 28th : Jerome takes over oncall, Rolf goes off on vacation.

    Downtime due to the DIRC: None.
