Go back Van de Graaff room experiments
A CO-60 source was placed 2" from the center of a detector, which was shielded from cosmics by 4" of lead, except for right below the source, where there was small pin hole through the lead. Placed directly above the source is a finger detector that is in hardware coincidence with either PMT.
PMT threshold: 40 mV
Finger Threshold: 30 mV
Event rate: 2.8 Hz
