Here is what happened today:

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


Run # Beam Dump magnet Collimator add coll Hardener 1" Al Radiator 25 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 Hz × 60 sec/min = 12.9 n/min
R(upstream) = 0.0272 e+/pulse
