BLM calibration

  • AL preparing documents for requirements and specs
  • Needs to be done at reasonable background levels, i.e., not with high dark current conditions from cavities.
  • Should this go hand in hand with scan to verify coverage after a long shut down period?
  • Add flow chart

View screen / BLM interlocks for tuning

  • AL preparing documents for requirements and specs
  • Is table and requirements enough? Or what should document look like?

FLASH/Darklight effect on MPS

  • Darklight and FLASH installation complete
  • Email from Luca Egoriti last week: hoping to put beam on the FLASH station (the old EMBD dump) as soon as the e-linac is back in shape, and since the shielding envelope has changed we foresee higher dose rates in the ehall coming from the target/dump. Hence, we wanted to let you know since there might be some MPS work to be done to accommodate the modifications
  • Recommissioning required for medium and high energy section.
  • 1kW for FLASH dump in pulse mode. 1W in continuous mode. There might be extra room for BLM thresholds ==> AL to follow up with Luca E.
  • original dump design was for 500W ?

2nd stage trip implementation

  • Final status of implementation?
  • What is left to do/needed?

Fibre

  • Do we have PMT?
  • What SiPMs are we looking to buy?

AOB

  • Do all channels already have an HV OK? Do some still need to be added to watchdog?
  • Making LICs for BL4N once cases are down a bit
