2459 Up 90A In Open Yes Out DU cylinder Beam check-in run.

R(beam down) = 1/160279 = 0.0000062 n/pulse
R(upstream) = 124/160279 = 0.00077 = e+/pulse

2460 Down 86A In Open Yes Out DU cylinder Beam check-in run.

R(beam down) = 0/160873 = 0 n/pulse
R(upstream) = 142/160873 = 0.00088 = e+/pulse

2461 Down 86A In Open Yes Down DU cylinder Beam check-in run.

R(beam down) = 33/160084 = 0.0002061 n/pulse
R(upstream) = 990/160084 = 0.00618 e+/pulse
About 86% of photons are coming from the radiator according to PS. Good
