Beam energy = 3 MeV

Horizontal beam position = 4.0 mm, vertical beam position = 0.0 mm.

Beam intensity at inj ~ 2.5e7

Detectors are positioned IN. Left arm = 36.54, right arm =  64.60 mm

Cycle time ~ 6 minutes

 

01:05

Target density still very unstable

 

02:45

Target density has dropped to ~1e9 and has been at that level for 30 minutes. We will try to move the target a bit and see if we can get an increase. Target position is currently x=-12400, y=2900
