Run Plan

Calibration

• Tune beam to 1 pass, Set HRSL(-) and HRSR(-) at 15 (-15) deg.

1. 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.

2. Momentum scane for BigBite calibration, H(e,e'p) Kin A 1,2,3.

• Energy change 1 pass to 2 pass.

3. Continue calibration of BigBite H(e,e'p), D(e,e'p) and C(e,e'p) Kin A 4,5, B 1,2 and C1

• 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.

4. Calibration of the HAND with H(e,e'p) Kin D1.

5. 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(-).

6. Continue calibration of HRSs with quasi elastic scattering C(e,e'p) Kin G 3,4

7. HAND neutron efficiency calibration.Kin E 1,2.

• Tune beam to 4 pass, switch HRSs polarity to HRSL(-) and HRSR(+).

8. D(e,e'pn), Establish triple coincidence at x>1 (Kin Pmiss = 250 MeV/c)

• Singles rates study
