Run # Beam Dump magnet Collimator Radiator 10 um Al Target Comments
2359 Centered In Open Out No Test radiator in/out

R(upstream) = 157/40244 = 0.0039 e+/pulse,
R(downstream) = 183/40244 = 0.0045 e+/pulse

2360 Centered In Open Centered No Test radiator in/out

R(upstream) = 898/40244 = 0.0223 e+/pulse,
R(downstream) = 1040/40244 = 0.0258 e+/pulse
About 83% of photons are coming from the radiator. No bad

2361 Up 2 mm In Open Up 2 mm No Test radiator in/out

R(upstream) = 730/40839 = 0.0179 e+/pulse,
R(downstream) = 867/40839 = 0.0212 e+/pulse

2362 Up 2 mm In Open Out No Test radiator in/out

R(upstream) = 172/41035 = 0.0042 e+/pulse,
R(downstream) = 258/41035 = 0.0063 e+/pulse
About 77% of photons are coming from the radiator. No bad

2363 Up 2 mm In Open Out No Test radiator in/out

Added 1" Al hardener against Cu bricks after vacuum window.
R(upstream) = 87/41037 = 0.0021 e+/pulse,
R(downstream) = 119/41037 = 0.0029 e+/pulse

2364 Up 2 mm In Open Up 2 mm No Test radiator in/out

Added 1" Al hardener against Cu bricks after vacuum window.
R(upstream) = 87/41037 = 0.0021 e+/pulse,
R(downstream) = 119/41037 = 0.0029 e+/pulse
About 88% of photons are coming from the radiator. No bad
