Run1 - January 2015

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)

1. Make a photocathode – SL5247-1 made
2. Test IHA2D00 – wires & stroke good, but data file odd vs. others
3. Hi-Pot IP – FE’r potted, but high again, vac readback not good
4. CHL 2K cooldown – maybe early, Monday Jan 12th
5. Install laser – Tue or Wed
6. Test laser RF trigger – after laser installed (1V, 10ns @ RF)
7. Verify beam line layout –documented below
8. Build elegant deck – working
9. Build qsUtility config file –documented below

Injector Setup and Mott Checkout (Wed Jan 14 - Fri Jan 16)

1. Restore beam to FC2 @ 6.3 MeV/c
2. Mott test: DAQ FADC/TDC synchronization
3. Mott test: event separation and transmission at 62MHz acceptable
4. Quad center BPMs for momentum measurement
5. Test harp IHA2D00 if ready for energy spread measurement
6. Scale cryounit for p=5.487 MeV/c and minimize energy spread
7. Precisely measure beam momentum
8. Measure beam emittance
9. Measure energy spread
10. Calibrate BCM to FC2
