Abstract :
Energy dependent counting losses occur in most pulsed-feedback preamplifiers due to the loss of those pulses which activate the recharge system. We describe a pulsed-feedback system that overcomes this inefficiency. The paper also discusses pulsed-light feedback as used with germanium gamma-ray spectrometers used at high energies and high rates where those losses become significant. Experimental results are presented.
