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

Run Description
5786 21 min, 6 sec
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
