Pulse circuits for the millimicrosecond range

This paper gives a review of the circuit techniques used in measurements on short pulses and the time intervals between pulses in the range 10¿9 to 10¿7 seconds, with particular reference to Nuclear Physics measurements. The circuits described have been developed for work with scintillation counters and spark counters and include pulse shaping circuits, pulse generators, amplifiers, scalers and recording oscilloscopes. Examples of the use of these circuits for high speed coincidence measurements, millimicrosecond time interval measurements and fast counting are given.
