Use only B-top (PG4) gas feed. Load with 6 psi of helium. All other valves disabled. Load 1070402011 as the starting shot. Expect this to have 3 mT of helium Expect to take approximately 20 shots. Jinseok Ko is the SL MP 460. Beam into gas. No fields. Looking for the angles of the MSE channels with respect to the trajectory of the beam by measuring the Doppler shift.

Physics Operator Comments
Apr 9 2007 10:57:54:720AM		Bill Rowan	Turned off observer. Loaded shot 1070402011. Segment 1 is on. Segments 2,3,4 are all off. PG4 (B-Top) is set for 1.59 s which I expect to produce 3 mT if the plenum pressure is 6 PSI. Enabled DNB gate valve
Apr 9 2007 11:14:52:363AM	1070409001	Bill Rowan	001. Successful shot. Beam fired during init and at the requested time. This caused the beam data not to be taken during the shot. No beam data. Gate valves were open during shot. For next shot, gates valves will be closed for 45 s after the shot.
Apr 9 2007 11:23:54:440AM	1070409002	Bill Rowan	002. Good shot. SL agrees with pressure and gate valves are closed as requested Beam fired only at the requested time. Did not fire during init. No beam data
Apr 9 2007 11:33:34:943AM	1070409003	Bill Rowan	003. Beam fired. Beam data available for this shot.
Apr 9 2007 12:10:42:880PM	1070409007	Bill Rowan	007. Increased the he pressure by 3 % Changed the pg4 pulse length from 1.59 to 1.63 SL noted that the pressure was restored to the original target.
Apr 9 2007 01:09:42:490PM	1070409010	Bill Rowan	010. Increased the He pressure because of shot to shot droop. The new pulse length is 1.68 s
Apr 9 2007 01:31:36:763PM	1070409014	Bill Rowan	014. Increased pressure by 3% at the request of the SL Increased the pulse length to 1.73 s
Apr 9 2007 01:38:19:640PM	1070409016	Bill Rowan	016. Increased the pressure at the request of the SL The pulse length for PG4 is now 1.78 s
