MPS Minutes 20230302

Present: BH, MA, RC, SR, MR, HH, RN, AL Commenced: 10:01am Adjourned: 10:30am

BLM force functionality

• Roll-out done by Mike this week.
• First test performed with Brandon. Forced one detector, and it was still possible to send beam
• First tests successful
• AL verified threshold and voltage settings are correct after roll-out
• For EMBD:LIC2 (on the detector page), the slider for HV is at zero, while the voltage seems on and the readback is at 500V. MR to look into this.
• Next step: Testing. AL to write up testing/commissioning procedure. This has priority.

E-linac Status

• Obtaining license will still take at least 6 weeks.

BLM position

• AL messaged Darren Blom to get remaining BLMs fixed in place
• Will pick a day when hall is open next week
• Darren suggested 3D printed option for mount of one of the low-energy detectors that was moved during work last year
• Even though darklight will be installed in high energy dump section, LICs should be fixed in place for now.
• Recommissioning will be required whenever changes to beamline are made

Post Mortem

• AL to do tests with RC next week to check functionality and readout
• Use LEDs and external trip for offline testing

Fibre

• No update

BLM calibration

• BLM calibration functionality will be implemented once BLM force functionality has been tested
• AL to finish document first

AOB

• ELBD:PMT0 detector should no longer cause a trip of the FSD, as it's not positioned along beamline anymore, but in front of egun window for monitoring
• MR to remove this detector from trip logic and detector ok check. Will require work permit and update of documentation
