Unpolarized Measurents:
A 2x4x8" aluminum brick was placed at the HRRL export in order to destroy the photon polarization. Rate measurements were made with the descriminator and HV settings used the past week. Then the constant fraction descriminator was replaced with a threshold descriminator on two detectors but not the reference detector.
ADC =0 => Reference Detector D
ADC = 1 => NaI
ADC=2 => Detector C
ADC = 3 => Detector A
channel # * 0.1675 ns/chan => ns
Default HV and CF descriminator
Matched HV and Threshold Descriminator
2 Runs were taken with the following settings
