Beam Parameters:

  • current 140 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
2527 Up
90A
In Open In Yes In D2O buttle Test radiator in/out.

-- pulses
R(bottom) = 0.000209 n/pulse -> × 180 Hz × 60 sec/min = 2.26 n/min
R(upstream) = 0.0107 e+/pulse

2528 Up
90A
In Open In Yes In DU cylinder 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.

2529 Down

In Open In Yes In DU cylinder Test radiator in/out.

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

2530 Down
86A
In Open In Yes Out DU cylinder 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.
