  • 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
