MPS meeting minutes – June 16th – 2022

Present:


MPS status

  • LIC0 trouble shooting
  • Argon flow started yesterday
  • Keiko updated signal PV in the alarm handler and archiver for former ELBT:PMT1A now ELBT:LICSP1 (spare channel)


S1 to S2 delay

  • the delay between stage 1 trip detection to stage 2
  • detect mode was fixed at 10us (plus some inherent delay through the FSD and timing system ~5us).
  • Delay is adjustable between 1us and 25us. Default is 10us.
  • EPICS indications for S1/S2 trips => Ricky to check what is indicated when at the moment and potentially adjust to avoid confusion


FLASH

  • anything since last week’s email?
  • Board modifications complete
  • Still need to update epics conversion factors
  • HH thinks the modified board will work for FLASH. Before I it can be install, Controls will need to change the conversion factors on

the EPICS screen. Basically all existing conversion need to be increased by 100.

  • Rod to let HH know who will be make the changes and HH will email the “updated” user manual.

E-Linac status

=> Brandon

AOB

  • The beam path restrictions are not really set up to make sure BLMs are running. Only checking HV for low-energy section
  • Can we implement this now for the medium and high-energy sections? Would this cause issues, when temporarily disabling detectors?
