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.
