Run Number Date User PMT High Voltage Experiment Description and observations Image
1095 12/05/2012 Marco Ham. RA1815 -1.80 (Camac) Gain Using plastic dark box, with LED pulse with 7 (on 5V) at 3.5 (on 15ns) with ~1kHz. It is important to note that the PMT pulse has ~30ns and the integration window has 60ns (the maximum from the coincidence module). If the pulse arrives too delayed (~+20ns), part of it may be outside the the integration window. File:1095.png
1096 12/05/2012 Marco Ham. RA1815 -1.80 (Camac) Gain Repeating run #1095 with the minimum light that still give some pulses once in a while.

1097 12/06/2012 Marco Ham. RA1815 -1.80 (Camac) Prototype Running prototype test (cosmic rays) with 08 tiles (boxes 01, 02, 04, 05) with refractive index 1.030. Trigger PMTs at -1.95kV. Start 09:05 (12/06) and finished 11:44 (12/06) with 200 events. File:1097.png
1098 12/05/2012 Marco Ham. RA1815 -1.80 (Camac) Gain Repeating run #1097 with more time. Problem with discriminator (3rd channel), triggering continuously. Turned everything off and changed to 5th channel. -
1099 12/05/2012 Marco Ham. RA1815 -1.80 (Camac) Gain Repeating run #1097 with more time. Start 12:33 (12/06) and finished 09:38 (12/10) with 7669 events. 1099.png
1113 01/16/2013 Marco Ham. RA1815 -1.80 (Camac) Prototype Repeating run #1099, to make sure system is working after long shut down (Christmas break). Few events just for test.
