PREX Main
Important Note for Shift Workers
- Post separate HALOG entry for status changes/events
- Please fill out the Shift Checklist at the beginning of the shift
- Access arrangement should be done through the Run Coordinator
- Documentation of Online Plots
- Documentation of all alarms
- Determining tasks and allocating responsibilities is up to the Shift Leader and shift crew to decide amongst themselves at the beginning of a shift
General Instructions for shift crew for parity running
- watch out for
- ion chambers
- collimator temps
- detector voltages in pengui (usl 5.6 V usr 5.2 V at 70 uA)
- BPM saturation
- position locks for > 1 uA: BPMA (x=0.2; y=-0.5) BPME (x=0.2; y=-0.5)
- raster : 12 by 7.2 in MCC units (width by height) raster synch/unsynced values in the white board outdated?
- make sure
- Charge feedback is on
- FFB ON (see FFB GUI: FF ON, FF DAC ON, EnergyModeRF ON)
- BeamMod ON after beam is established (BPM gains set and stable and FFB ON)
Before your shift
- First!! Please read and sign the safety documentation in the counting house. A readable version can be found here!
- Second!! Please sign up for more shifts
Shift Workers and Their Responsibilities
- Shift Leader - Point of contact between RC/MCC and shift workers; takes data
- Target Operator - Monitors the target, moving it as necessary
- Analysis Shift Worker - Assist shift crew in data taking, makes sure online analysis is up to date
- Weekly Analysis Coordinator (WAC) - Performs the offline analysis checks
- Run Coordinator (RC) - Responsible for safe and efficient running of the experiment
