summary what was been done

  • current 140 mA
  • pulse width 2 us
  • rep rate 180 Hz
  • E = 25 MeV


Run # Beam Dump magnet Collimator add coll Hardener 1" Al Radiator 10 um Al Target Comments
2502 Up
90A		 In Open In Yes In DU cylinder Test radiator in/out.

120664 pulses
R(bottom) = 0.0012 n/pulse -> ×180×60 = 12.9 n/min
R(upstream) = 0.0272 e+/pulse

2503 Up
90A		 In Open In Yes Out DU cylinder Test radiator in/out.

121258 pulses
R(bottom) = 0 n/pulse
R(upstream) = 0.00091 e+/pulse
About 97% of photons are coming from the radiator according to PS. Very Good

2504 Down
86A		 In Open In Yes In DU cylinder Test radiator in/out.

R(bottom) = 0.00137 n/pulse -> ×180×60 = 14.8 n/min
R(upstream) = 0.0319 e+/pulse

2505 Down
86A		 In Open In Yes Out DU cylinder Test radiator in/out.

122247 pulses
R(bottom) = 0 n/pulse
R(upstream) = 0.000908 e+/pulse
About 97% of photons are coming from the radiator according to PS. Very Good
