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.
