Nuclear detector system with reduced dead-time processor circuit

摘要

For use in a well logging tool which responds to randomly spaced pulses of different amplitudes, a pulse processing circuit featuring reduced dead-time is incorporated. Typically, it can be used with either a gamma ray or neutron detector. The circuit enables mixed amplitude pulses with irregular spacing to be processed with relatively different rise and fall times. The circuit processes the trailing or following portion of a pulse differently from the leading or rising portion to enable a separate following second pulse to be observed.
