summary what was been done

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. Good

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. Good

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.

R(upstream) = 777/50837 = 0.0153 e+/pulse,
R(downstream) = 847/50837 = 0.0167 e+/pulse
About 86% of photons are coming from the radiator. Good

2365 Up 2 mm In Open Up 2 mm No Test radiator in/out. Now 2" Al hardener against Cu bricks after vacuum window.

R(upstream) = 574/41235 = 0.0139 e+/pulse,
R(downstream) = 717/41235 = 0.0174 e+/pulse

2366 Up 2 mm In Open Out No Test radiator in/out.

R(upstream) = 117/41035 = 0.0028 e+/pulse,
R(downstream) = 136/41035 = 0.0033 e+/pulse
About 80% of photons are coming from the radiator. Good

2367 Down 2 mm In Open Out No Test radiator in/out. Removed 2" Al hardener

R(upstream) = 160/41036 = 0.0039 e+/pulse,
R(downstream) = 199/41036 = 0.0048 e+/pulse

2368 Down 2 mm In Open Down 2 mm No Test radiator in/out.

R(upstream) = 628/40639 = 0.0154 e+/pulse,
R(downstream) = 714/40639 = 0.0176 e+/pulse
About 75% of photons are coming from the radiator. Good

2369 Down 2 mm In Open Down 2 mm No Test radiator in/out. Added 1" Al hardener against Cu bricks after vacuum window.

R(upstream) = 454/40640 = 0.0111 e+/pulse,
R(downstream) = 536/40640 = 0.0132 e+/pulse

2370 Down 2 mm In Open Out No Test radiator in/out.

R(upstream) = 98/40639 = 0.0024 e+/pulse,
R(downstream) = 112/40639 = 0.0027 e+/pulse
About 78% of photons are coming from the radiator. Good

2371 Up 2 mm In Open Up 2 mm No Test radiator in/out to reproduce previous result. Same 1" Al hardener against Cu bricks after vacuum window.

R(upstream) = 935/40641 = 0.0230 e+/pulse,
R(downstream) = 1050/40641 = 0.0258 e+/pulse

2372 Up 2 mm In Open Out No Test radiator in/out.

R(upstream) = 153/40640 = 0.0038 e+/pulse,
R(downstream) = 144/40640 = 0.0035 e+/pulse
About 84% of photons are coming from the radiator. Good

2374 Up 2 mm In Open Up 2 mm DU plate DU plate oriented 45 and 45 degree. Same 1" Al hardener upstream of collimator.

Too short

2375 Up 2 mm In Open Up 2 mm DU plate Same. Rerun 2374

Too short
