Timing filter Amp Configuration

Course gain: x6

Fine gain: at minimum

Integrate (nS): 500nS

Diff (nS): Out

Invert/Noninverted: Non-Inv

Timing filter amp used to scale analog signal from NaI detector in plateau measurements

Dual Timer Configuration

Setup such that input discriminated pulse is at width ~200ns

Out feeds into scalar for counts

Top half of dual timer used to gate signal for scalar in plateau measurements

Operating Point

A quick glance at the data shows that the optimal operating point may be 1000V with a discriminator threshold of ~135mV. This gave a signal:noise = ~1.8

Will run some shielded source in/out measurements at this point
