This page will be used for the Run 1 experiment and analysis
Shift Schedule
Shift Worker Duties
- Beam Driver
Beam setup: gun + laser + spin + beam to Mott BCM & target motion FSDs enabled Vacuum levels reasonable Magnet and RF setup saved PITA adjusted for IHWP IN/OUT
- DAQ Driver
Start/Stop DAQ entering correct run information Monitor event rates and maintain dead time <5% Coordinate run start/stop with Beam and Analysis Drivers
- Analysis Driver
Runs decoded, analyzed and promptly inspected Run # and information logged onto run sheets Elastic events counted for IHWP=IN/OUT
Prep Work (through Tuesday Jan 13)
- Make a photocathode – SL5247-1 made
- Test IHA2D00 – wires & stroke good, but data file odd vs. others
- Hi-Pot IP – FE’r potted, but high again, vac readback not good
- CHL 2K cooldown – maybe early, Monday Jan 12th
- Install laser – Tue or Wed
- Test laser RF trigger – after laser installed (1V, 10ns @ RF)
- Verify beam line layout –documented below
- Build elegant deck – working
- Build qsUtility config file –documented below
Injector Setup and Mott Checkout (Wed Jan 14 - Fri Jan 16)
- Restore beam to FC2 @ 6.3 MeV/c
- Mott test: DAQ FADC/TDC synchronization
- Mott test: event separation and transmission at 62MHz acceptable
- Quad center BPMs for momentum measurement
- Test harp IHA2D00 if ready for energy spread measurement
- Scale cryounit for p=5.487 MeV/c and minimize energy spread
- Precisely measure beam momentum
- Measure beam emittance
- Measure energy spread
- Calibrate BCM to FC2
