Coincidences 03/24/04

(Jim Braun and Mark Krasberg)



Data taken using two rev 3 DOMs. The DOMs were at -5 degrees centigrade in the small freezer. A xenon flashlamp was used to fire the DOMs simultaneously. The data collector corrected the time stamps using a crude DOR round trip time where the rapcal waveforms were ignored. The lights in the room were turned off for half of the run (this helped with the noise).

The first graph is for a run where the flashlamp was on. The second graph is for a run where the flashlamp was off.


2 doms, xenon flashlamp firing, simple rapcal timing correction applied

2 doms, no light source, random coincidences, timing correction applied
