COINCIDENCE-ANTICOINCIDENCE AND LINEAR GATE CIRCUITS
Wolfhard Klein · OSTI OAI (U.S. Department of Energy Office of Scientific and Technical Information) · 1959
Coincidence-anticoincidence installations are required for registering an event only if one or more other events occur simultaneously or non- simultaneously. The optimum coincidence-resolving capacity of an arrangement is dependent upon the input-pulse form and the amplitude range. Adjustment is best made via pulse-formers. The function of the actual coincidence-anticoincidence stages is usually based on one of three general circuit paiterns: multiplicative mixture (Bothe circuit), additive mixture, possibly with bent characteristic lines (Rossi circuit) and bridge circuits. Examples of these three types of circuit are discussed. If an amplitude criterion is required in addition to the coincidence criterion, there are two general types of circuit: amplitude selpetion before coincidence selection and coincidence selection before amplitude selection. Examples of these types of circuit are also discussed. (auth)
