D2n Run Plan 2020

Rough / High-level sketch of d2n kinematic settings

Reduced kinematics list to accommodate limited beam time (dropped 1/4 of kinematics)

      ---------  Beam Params ----------
            E_beam = 10.4 GeV/c
            I_beam = 30 uA
            P_targ = 0.50
            P_beam = 0.80

          ---------  HMS ----------
       E'    theta    x        Q2       W
*C    -4.0   20.0     0.418    5.018   2.806 [Starting here] --  Only setting compatible with SOLID Cherenkov small-angle test.
 A    -4.2   13.5     0.207    2.414   3.178
 B    -4.2   16.4     0.305    3.554   2.993

          --------- SHMS ----------
       E'    theta    x       Q2      W
*X    -7.5   11.0     0.527   2.866   1.859  [Starting here]
 Y    -6.4   14.5     0.565   4.240   2.036
 Z    -5.6   18.0     0.633   5.701   2.046

Run / Shift Schedule

• We started taking on Swing on Aug 7 (took a few days for beam to stabilize)
• Beam is scheduled to turn off 8am, Sept 21 (roughly 6 weeks) [1]
• Hall C Shift Schedule
