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

Run	Description
5822	Ba-132 + Al rod, only counting with detector 180-3 (no TDC) 10 min 56 sec long, 459 Hz
5823	empty rod, only counting with detector 180-3 (no TDC) 11 min 49 sec long, 439 Hz

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.
