Start-up run plan
Item 1-4 to be done by the MCC. RC will be at the MCC and help communicating with the shift crew.
- Beam and target alignment
1. Beam to the dump. Septum off, no target. 2. ion chamber calibrations. Yves has a special target to insert. 3. Beam and target alignment (1x1 raster, carbon hole target, wire target, S3 scintillator. setting ready for Yves). 4. Set corrector magnets with septum on. Beam to dump. Will be done quickly.
Once Yves is done and MCC is ready to deliver CW beam to Hall A:
- Detector checkout:
- do in parallel with optics runs.
- Check online replay plots. Experts will be at the CH to check.
- scaler rates: post snapshots to halog
- Optics calibrations (Experts: Bogdan, John, Vardan, ...)
- Set the spectrometer magnets: 
- Start with RHRS. Set LHRS (positive polarity) RHRS (negative polarity).
- Once the right arm is finished, move on to the LRHS. Set LRHS (neg) RHRS (pos).
- BPM calibration. Instruction: BPM
