Au-196 #5 irradiation
The link below will take you to an analysis of the photon spectrum observed when a mixture of Au + San in a crucible is irradiated for 1 hour using a 44 MeV, 2kW electron beam incident on a 4 mm W converter
The link below will take you to the 0.002" thick gold foil measurements
Barium Oxide BaO
Y-88 foil
Nickel normalization foils

| 5790 | Ba-133 source, TDC not getting hits | |
| 5791 | Ba-133 source , TDC not getting hits | |
| 5792 | Ba-133 source, TDC not getting hits | |
| 5817 | Gold foils, only counting with detector 180-3 (no TDC) 8 min 2 sec long, 556 Hz | |
| 5818 | Ni foil F1, only counting with detector 180-3 (no TDC) 6 min 31 sec long, 399 Hz | |
| 5819 | Ni foil B1, only counting with detector 180-3 (no TDC) 7 min 36 sec long, 417 Hz | |
| 5820 | empty, only counting with detector 180-3 (no TDC) 8 min 18 sec long, 396 Hz | |
| 5821 | Ba-132, only counting with detector 180-3 (no TDC) 6 min 1 sec long, Hz |
Due to the low rates we reconfigured the setup putting the two detectors closer together
