Abstract
A discriminator circuit for use with a scintillation detector, wherein the scintillation detector output is fed to a time discriminator and the output of the time discriminator is fed via a short precision delay device to one input terminal of a transmission gate device. The detector output signal is also fed to a fast energy discriminator whose output is furnished as an enable signal to the other input terminal of the transmission gate device, providing time output pulses. Timing pulses from the transmission gate device are furnished to a long non-precision delay device and then to one input terminal of a transmission gate. The detector output signal is also fed through a slow energy discriminator and an enable line to another input terminal of the last-named transmission gate, providing energy output pulses in an energy output line which are furnished to the subsequent portion of the system.
