- Tune beam to 1 pass, Set HRS(L) and HRS(R).
- Move the HRSs to 15 (-15) Deg. HRSs calibration C(e,e') (elastic) with/ without sleeves.
- Move HRS(R) to 12.5 deg, 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.
- 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
- 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.
- Switch the polarity of HRSs.
- Continue calibration of HRSs with quasi elastic scattering C(e,e'p) Kin ____.
- HAND neutron efficiency calibration. Put the BigBite at 99 Deg (magnet on detector off) and HAND behind. Kin E 1,2.
BigBite angle change. (Rotate BB to an angle so that there will be no obsticle in the line of sight from target to the n-array).
- n-array commision, Kin B1
- Change set-up to BB and N-Array both at 99 Deg + Energy change 2 pass to 4 pass
- Singles rates study
- D(e,e'pn) X<1, Kin D1
End of commision
- D(e,e'pn) X>1, Kin E1
- SRC Run, low Momentum range, Kin F1
- SRC Run, High Momentum range, Kin F2
