summary what was been done

Run # Beam Dump magnet Collimator Hardener Radiator 10 um Al Target Comments
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 -> ×180×60 = 2.2 n/min
R(upstream) = 990/160084 = 0.00618 e+/pulse
About 86% of photons are coming from the radiator according to PS. Good

2462 Up
90A		 In Open Yes Up DU cylinder Beam check-in run.

R(beam down) = 0.000362 n/pulse -> ×180×60 = 3.9 n/min
R(upstream) = 1064/165434 = 0.00643 e+/pulse
About 88% of photons are coming from the radiator according to PS. Good

2463 Up
90A		 In Open Yes Up Out Beam check-in run.

R(beam down) = 0 n/pulse
R(upstream) = 0.0062 e+/pulse

2464 Down
86A		 In Open Yes Down Out Beam check-in run. Short beam off

R(beam down) = 0.000029 n/pulse
R(upstream) = 0.0055 e+/pulse

2465 Down
86A		 In Open Yes Down Out Beam check-in run. Redoing 2464

R(beam down) = 3/160876 = 0.000019 n/pulse
R(upstream) = 1053/160876 = 0.0065 e+/pulse

2466 Down
86A		 In Open Yes Down DU cylinder Long production run

R(beam down) = 243/972019 = 0.00025 n/pulse -> ×180×60 = 2.7 n/min
R(upstream) = 0.0064 e+/pulse

2467 Up
90A		 In Open Yes Up DU cylinder Long production run

R(beam down) = 292/972017 = 0.0003 n/pulse -> ×180×60 = 3.2 n/min
R(upstream) = 0.00656 e+/pulse

2468 Up
90A		 In Open Yes Out DU cylinder Long production run

R(beam down) = 0/162265 = 0 n/pulse
R(upstream) = a/162265 = 0.00170 e+/pulse
About 74% of photons are coming from the radiator according to PS. Bad

2469 Up
90A		 In Open Yes Out DU cylinder Long production run. Bean was turned up a little by operator's view screen.

R(beam down) = n/pulse
R(upstream) = = 0.00 e+/pulse
Still bad

Removed dump magnet and recalibrated beam


Run # Beam Dump magnet Collimator Hardener Radiator 25 um Al Target Comments
2459 Up
90A		 In Open Yes Up DU cylinder Beam check-in run.

R(beam down) = n/pulse
R(upstream) = = e+/pulse
