View source for Check-list For taking Counting runs and Going back to Production

* Before taking Counting Runs:
** Turn '''ON S0 and S3''' ('''L0.0, L0.1, L0.2, L0.3, L0.4''' in both arm's HV GUI)
** For '''Raster Check in C-Hole'''
*** Ask low current <2uA such that '''T1 rate <100kHz'''
*** Ask for appropriate raster size and position lock as in '''WHITE BOARD'''
*** Follow [[HVgui | Checking the HV]] HOW TOs for shift crew if you need to
*** You can start runs once the '''position and HV read-back are settled'''
** For '''Detector alignment Check'''
*** Ask for low current (0.3uA on Ca-48 target)
*** Ask for appropriate raster size and position lock as in '''WHITE BOARD'''
*** make sure the '''T1 rate is ~200kHz'''
*** turn '''ON VDC''' ('''L6.0, L6.3''' in LHRS and '''L4.5, L4.7''' in RHRS) if the T1 rate is good
*** set Downstream MAIN detectors HV to '''-1900V''' ('''L1.1 in both arms'''), and turn them ON
*** once the position and HV read-back are settled, take runs
*** follow [[Taking MAIN detector Counting Run | Taking MAIN detector Counting Run]] if you need to analyse data
* Once you are done with counting Runs:
** Turn '''OFF S0, S3, Downstream MAIN detectors, and VDCs''' and set '''Downstream MAIN detectors HV to 0.0V'''
** Ask for high current (production) only after turning OFF the detectors mentioned in the previous step
