Shift Instructions
- The septa current must be set to match each new spectrometer dipole momentum setting.
- Make sure to acknowledge the DAQ popup messages for Start and End of every run.
- Keep a stripchart running of the septa currents. Log any fluctuations, and notify Run Coordinator.
- Take bleedthru measurement once a shift
- Make sure you know exactly what you are doing if operating the Sieve Slit. Compare to this photo
How Tos
- How to run the g2p DAQ
- How to Set the Spectrometer and Septa Magnets
- How to Cycle the Quadrupoles
- How to make vertical correction to target insert
- How to take HARP scan
- How to recover the beam after an extended (>4 hour) down: G2p-beam-recovery
- How to recover BPM positions after a long beam trip or tune change
- How to check Bleed-thru
- How to Set the Slow Raster
- How to check IHWP change in state and alarm
- How to control the Hall A Dump Camera Light

Useful Links
- The g2p Analysis Guide
- Beamline Component locations
- Chicane Positions
- MCC Whiteboard +offsite access to logs (courtesy Brad)
- d2n HowTo (Please note some info is out of date).
- Spring11 HowTo (Please note some info is out of date).
- Online Replay Guide (detailed) (Old Transversity Guide) (Please note some info is out of date).
- mysql Run Database for gep/g2p
- Hall A Moller
Miscellaneous Notes
- The Coda configuration is: LHRS, RHRS
- To read the Hall A current : Open Monticello / Wall / Hall A GUI, and look at the 1H00 BCM.
- To open the Hall A tools screen, as hacuser type "NewTools" which pops up EOSMenu. Select "HLAmain".
- To start a Stripchart, click toolbox on bottom of desktop menu
- Only IHWP1 flips the beam helicity. IHWP2 is passive.
