General
- Dave M. showed some slides regarding helium contamination in Hall C and it's effect on PMT's installed in the Hall
- 2.2 and 6.6 GeV is needed for detector, optics, and acceptance checkout during the Fall 2017 commissioning run
- We have 1 week to perform the commissioning
- There is no time to take our time with performing checkouts
- Everything that is required to perform the checkouts needs to be available and planned out prior to commissioning
- We need to develop a plan for measuring the trigger efficiencies
- The trigger/DAQ configuration requirements for the upcoming experiments need to be provided as soon as possible to the trigger/DAQ group
- Preliminary commissioning plans have been requested from each of the individual detector groups by next meeting
Beam Line
- The super harps have been pulled from the Hall to be re-fiducialized
- Dave G. contacted John and Kieth regarding the bug BPMs
- They had the wrong sign during the Spring 2017 KPP run
- This was known since work was being done on the electronics and software side
- The known helium leak in the dump that was discovered during the KPP run is being investigated
- The leak limits the current that can be delivered into the Hall and must be resolved prior to the Fall commissioning run
- The leak cannot be observed now however, the helium flow has just been restored so they will check again after some time has elapsed
- Everything else in the beam line appears to be good to go
Trigger/DAQ
- The electronic dead time measurement is currently roughed in although it needs to be checked throughly
