  • Water pump GUI password protected, #1891
  • Network errors messages – in progress
    • Need to specifiy a port number for all CArepeaters - thus need to reboot all IOC-type machines. Need to find good time for miceecserv reboot.
    • Possibly related to the Watchdog failure, which hasn't re-appeared.


Spectrometer solenoids
  • Commissioning of Change over water solenoids for the SS diode absorber trays- T. Hartnett – complete, new tank installed, plumbing to be completed prior to re-test.
Focus Coil
  • FC Data logger GUI to be tested and verified – ongoing:
    • have access to the QPS data itself; have a plug-in to get this Labview data into Excel, but need to understand the channel mapping
    • Need a Windows PC running Labview client (rdesktop in) - can put on one of the Hall Probe machines
  • PT100’s on FC in R9 to be fitted – ongoing 0 sensors will be glued leave till summer?
  • FC power supply failure – repair with Sorensen
Hydrogen System
