2385 Up 2 mm In Open Out DU plate Beam check-in run. Beam hardener off.

R(beam 45 left) = 6/173553 = 0.0000346 n/pulse
R(beam 45 right) = 0/583758 = 0.0 n/pulse
R(beam down) = 15/173553 = 0.0000864 n/pulse

Beam was lost

2386 Up 2 mm In Open Up 2 mm DU plate Beam check-in run. 1" of Al hardener in front of upstream radiator.

R(beam 45 left) = n/pulse
R(beam 45 right) = n/pulse
R(beam down) = n/pulse
R(upstream) = e+/pulse
About 88% of photons are coming from the radiator. Good
