Summary of the day

  • current 120 mA
  • pulse width 2 us
  • rep rate 180 Hz
  • E = 25 MeV


Run # Beam Dump magnet Collimator Hardener 1" Al Radiator 10 um Al Target Comments
2479 Up
90A		 In Open Yes In DU cylinder Beam check-in run. Additional collimator in

R(beam down) = 0.000689 n/pulse
R(upstream) = 0.01667 = e+/pulse

2480 Up
90A		 In Open Yes Out DU cylinder Beam check-in run.

R(beam down) = 0.000018 n/pulse
R(upstream) = 0.00116 = e+/pulse
About 93% of photons are coming from the radiator according to PS. Good

2482 Down
86A		 In Open Yes In DU cylinder Beam check-in run.

R(beam down) = 0.000717 n/pulse
R(upstream) = 0.0164 = e+/pulse

2483 Down
86A		 In Open Yes Out DU cylinder Beam check-in run. Beam lost.

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

  • current 160 mA
  • rep rate 180 Hz
Run # Beam Dump magnet Collimator Hardener 1" Al Radiator 10 um Al Target Comments
2488 Down
86A		 In Open Yes Out DU cylinder Beam returned without VS. Beam check-in run. Additional collimator in

R(beam down) = 0 n/pulse
R(upstream) = 0.00116 = e+/pulse

2489 Down
86A		 In Open Yes In DU cylinder Beam check-in run.

R(beam down) = 0.00057 n/pulse
R(upstream) = 0.0129 = e+/pulse
About 91% of photons are coming from the radiator according to PS. Good

2490 Up
90A		 In Open Yes In DU cylinder Beam off.
2491 Up
90A		 In Open Yes In DU cylinder Beam check-in run.

R(beam down) = 0.000569 n/pulse
R(upstream) = 0.01198 = e+/pulse

2492 Up
90A		 In Open Yes Out DU cylinder Beam check-in run.

R(beam down) = 0 n/pulse
R(upstream) = 0.00080 = e+/pulse
About 93% of photons are coming from the radiator according to PS. Good


Good beam, good turning. So there are 2492production runs

Run # Beam Dump magnet Collimator Hardener 1" Al Radiator 10 um Al Target Comments
2494 Up
90A		 In Open Yes In DU cylinder Additional collimator in. Long production run

190006 pulses R(beam down) = 0.00063 n/pulse -> ×180×60 = 6.8 n/min
R(upstream) = 0.0142 = e+/pulse

2494 Up
90A		 In Open Yes In DU cylinder Additional collimator in. Long production run

190006 pulses R(beam down) = 0.00063 n/pulse -> ×180×60 = 6.8 n/min
R(upstream) = 0.0142 = e+/pulse

2494 Up
