Notes
- PLEASE make sure to acknowledge the DAQ popup messages for Start and End of every run.
- The Coda configuration is: LHRS, RHRS
- Hall A current : Open Monticello / Wall / Hall A GUI, and look at the 1H00 BCM.
- For Hall A tools screen, on hacuser type "NewTools" which pops up EOSMenu. Select "HLAmain".
- For Stripchart, click toolbox on bottom of desktop menu
- Keep a stripchart running of the septa currents.
- IHWP1 flips the beam helicity. IHWP2 is passive (actually a full wave plate) and will not flip the helicity. The epics var for IHWP2 is IGL1I00DIOFLRD :13056 means the passive wave-plate is in. 8960 is out..
