Minutes - Grad Student Meetings

TODO

Add comparison directory on xem2 web

Changing trigger-to-trigger check reftime cuts (reset)

Look at april2020 update (develop) goodscinhit, etc.

Summary page of responsibilities (help / experts)

• Read and try to understand specific aspects
• Make simplified documentation for each task (need enough information)

What to like to know: - parameter names and short descriptor - example diagnostic plots for comparison - Things to watch out for.

On shift data integrity checks - SHMS hodoscope HV, DC HV, ROCS, CODA - Radiator during J-psi was breaking things (DAQ problems, ROCS) - DC HV and HODO HV - Beam position locks (orbit locks) - Changing magnets and going to MOL if needed! (need to look at strip charts if avail?) - G guidance for alarms may give relevant info for shift takers (that don't read). - Communicating effectively with shift-takers. Make good links, but no good suggestions as of now. - Turning the rotation camera back on: https://logbooks.jlab.org/entry/3910814 - Refill a magnet spectrometer magnet with LN2 - Tracking efficiency vs. runnumber plots. (Some report_output reader / consolidator script)

Parameters for HCANA - know all of them. - example: dy/dz and dx/dz 'theta' and 'phi' - example: flags for tracking - example: momentum offsets

Think about tasks that aren't production - Deadtime studies of the fADC - are the momentum settings of go_magnets correct? (saturation effects in magnets) - delta acceptance study. - Efficiencies of cherenkov / calorimeter - Trigger settings / efficiencies rate - CSB (EMC), pion contamination - charge, position offsets - Survey and alignment reports - trigger thresholds - sys errors on nCer needs separate study
