Au-196
crucible #5 Gold + Sand irradiation
The link below will take you to an analysis of the photon spectrum observed when a mixture of Au + Sand in a crucible is irradiated for 1 hour using a 44 MeV, 2kW electron beam incident on a 4 mm W converter
Gold Foil
The link below will take you to the 0.002" thick gold foil measurements

Group 2
Due to the low rates we reconfigured the setup putting the two detectors closer together
| Run | Description | |

| 5828 | Coincidence, sand+crucible, only counting with detector 180-3 (no TDC) 15 hrs, 4 min 21 sec long, 47Hz, Det B HV OFF, Det B Coincidence window was more than 400 nsec | |
| 5829 | Coincidence, Au+sand+crucible #5 , 200 ns Coincidence window, no TDC hrs, min sec long, 23 Hz, Det B HV ON, ROC crashed after 45 hours 28 minutes, 285302 events recorded, scaler says 199440 seconds for run time=> 55 hours, I think the run lasted 2 hours assuming a 40 Hz counting rate and 285302 events, I think Det B warmed up during run, noise went high and high counting rate made ROC crash. | |
