Swansen, J E

Two areas for reducing coincidence deadtime have been investigated, analog and digital. The analog work includes use of a commercially available hybrid preamplifier discriminator useful to at least 150 kpps/channel with present detectors and added circuitry for combining multiple channels. The digital work includes reducing OR gate deadtime and the introduction of a derandomizing buffer at the input of the shift-register section. Providing benefits to 1 Mpps, the combined efforts of this work have reduced the six-channel coincidence deadtime from approx. 2.4 to approx. 0.7 ..mu..s. 2 references, 14 figures.
