NaI detector, -1030V, 300 mV threshold on gate channel, signal ADC4

Run #	Beam	Dump magnet	Collimator	Radiator 10 um Al	Target	Comments
2359	Centered	In	Open	Out	No	Test radiator in/out. R(upstream) = 157/40244 = 0.0039 e+/pulse, R(downstream) = 183/40244 = 0.0045 e+/pulse
2360	Centered	In	Open	Centered	No	Test radiator in/out. R(upstream) = 898/40244 = 0.0223 e+/pulse, R(downstream) = 1040/40244 = 0.0258 e+/pulse About 83% of photons are coming from the radiator. Good
