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)

Pulse shaper used for 3of4 [1]

Procedure to take CW beam

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
