Calibration
- Tune beam to 1 pass, Set HRSL(-) and HRSR(-) at 15 (-15) deg.
- HRSs calibration with C(e,e') (elastic) with/ without sleeves.
- Move HRS(R) to 12.5 deg change polarity to HRSR(+), Set BigBite at 68 Deg.
- Momentum scane for BigBite calibration, H(e,e'p) Kin A 1,2,3.
- Energy change 1 pass to 2 pass.
- Move BigBite to backward angle (should allow HRSR at ~70 deg)
- Put the Neutron array (without the lead wall) at 50 Deg and 15 meters from target. Calibration of the HAND with H(e,e'p) Kin D1.
- Continue calibration of HRSs with quasi elastic scattering C(e,e'p) Kin G 1,2.
- Put the BigBite at 99 Deg (magnet on detector off) and HAND behind and install lead wall. Switch the polarity of HRSs to HRSL(+) and HRSR(-).
- Continue calibration of HRSs with quasi elastic scattering C(e,e'p) Kin G 3,4
- HAND neutron efficiency calibration.Kin E 1,2.
- Tune beam to 4 pass, switch HRSs polarity to HRSL(-) and HRSR(+).
- Singles rates study
