Beam Parameters:

  • current 160 mA
  • pulse width 2 ns
  • rep rate 180 Hz
  • E = 25 MeV

Initial Test for Verification

Run # Beam Dump magnet Collimator add coll Hardener 1" Al Radiator 25 um Al Target Comments
2546 Up
90A
In Open In No In H20 bottle Test radiator in/out.

R(bottom) = 2.5E-4 n/pulse -> × 180 Hz × 60 sec/min = 2.70 n/min
R(upstream) = 40.9E-3 e+/pulse

2547 Up
90A
In Open In No Out H20 bottle Test radiator in/out.

R(bottom) = 6.1E-6 n/pulse -> × 180 Hz × 60 sec/min = 0.06 n/min
R(upstream) = 1.68E-3 e+/pulse
About 96% of photons are coming from the radiator according to PS.

2548 Down

In Open In Yes In H20 bottle Test radiator in/out.

-- pulses
R(bottom) = -- n/pulse -> × 180 Hz × 60 sec/min = -- n/min
R(upstream) = -- e+/pulse

2--- Down
86A
In Open In Yes Out H20 bottle Test radiator in/out.

-- pulses
R(bottom) = -- n/pulse -> × 180 Hz × 60 sec/min = -- n/min
R(upstream) = -- e+/pulse
About --% of photons are coming from the radiator according to PS.
