Cycling HMS to higher momentum</p><p>5)  During swing beam off until 22:50. Did a low current BCM calibration run until 23:50.</p><p>6) Midnight start kin2B dummy target with all SHMS paddles ON to match an earlier run of kin2B LH2. Beam was not good and finished around 2:00am.</p><p>7) Was able to move the HMS to 33.53 for kin2A kinematics. Turned off all SHMS X1 paddles except 6-8 and X2 paddles except 6-9.</p><p>8) Decide to run at 10uA and 85% livetime for kin2A for LH2.!
