run 2703 start 16:03 stop 16:57  5 M events

discussion with 4 Pm meeting group about plan...

run 2754: start 16:59 stop 16:59 short test run 



17:00 - 17:45: reconfigure target, NMR measurement

(34%) and go to nitrogen pressure curve.



run 2755 start 17:52 stop 17:55 - stop for Vince to make adjustments to high voltage



Pressure at 0 reads -8, so offsets need to be added back in



run 2756 start 18:04 stop 18:31 pressure = 0 (gauge reads -8)

run 2757 start 18:35 stop 18:47 pressure = 96+8 = 104

run 2758 start 18:49 stop 19:03 pressure = 189+8 = 197

run 2759 start 19:06 stop 19:22 pressure = 396+8 = 404

run 2760 start 19:23 stop 19:33 pressure = 613+8 = 621

run 2761 start 19:34 stop 19:44 pressure = 780+8 = 788

run 2762 start 19:48 stop 20:01 pressure = 780+8 = 15 psig



go to 3He pressure curve, do shift checklist



run 2763 start 20:12 stop 20:23 pressure = 0 (gauge reads -5)

run 2764 start 20:25 stop 20:36 pressure = 15 psig

run 2765 start 20:37 stop 20:48 pressure = 45 psig

run 2766 start 20:49 stop 21:01 pressure = 74 psig

run 2767 start 21:03 stop 21:11 pressure = 105 psig

run 2768 start 21:13 stop 21:26 pressure = 135 psig



21:35: Call MCC and ask them to insert the half-wave plate.

Go and warn Halls B and C about this. P_targt ~ 45.4%, Kin 

setting #10 on pol 3He longitudinal.



run 2769 start 22:00 stop 22:46, 2 M events

run 2770 start 22:47 stop 23:29, 2 M events



NMR measurement, P~42.1%



run 2771 start 23:34, stops after end of shift
