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

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
