summary what was done
| Run # | Beam | Dump magnet | Collimator | Radiator | Target | Comments |
|---|---|---|---|---|---|---|
| 2339 | Up 2 mm | In | Open | Up 2 mm | No | PS Rate is: R(upstream) = 2648/35092 = 0.075 e+/pulse, R(downstream) = 3191/35092 = 0.091 e+/pulse |
| 2341 | Up 2 mm | In | Open | Out | No | PS Rate is: R(upstream) = 1088/35494 = 0.031 e+/pulse, R(downstream) = 1328/35494 = 0.037 e+/pulse |
| 2342 | Down 2 mm | In | Open | Out | No | PS Rate is: R(upstream) = 1586/36678 = 0.043 e+/pulse, R(downstream) = 1888/36678 = 0.051 e+/pulse |
| 2343 | Down 2 mm | In | Open | Down 2 mm | No | PS Rate is: R(upstream) = 2232/35488 = 0.063 e+/pulse |
| 2344 | Centered | In | Open | Centered | No | PS Rate is: R(upstream) = 2683/35095 = 0.076 e+/pulse |
| 2345 | Centered | In | Open | Out | No | PS Rate is: R(upstream) = 1039/35094 = 0.029 e+/pulse |
| 2346 | Centered | In | Open | Out | No | PS Rate is: R(upstream) = 1286/35885 = 0.036 e+/pulse. Improved shielding around dump. |
| colspan="6" | Based on the previous results the beam is total crap, so beam turn up. | |||||
| 2347 | Centered | In | Open | Out | No | PS Rate is: R(upstream) = 1286/35885 = 0.036 e+/pulse. Improved shielding around dump. |
