A new shunt‐series amplifier section was developed for fast rise time pulse amplifiers intended primarily for use with accelerator beam probes, solid state detectors, and fast ionization chambers. Design equations for the gain section were derived from a high frequency model and were validated by computer analysis and experimental results. Two amplifiers were built, with three gain sections cascaded in each. The gain of these amplifiers was 270 and 135, and the rise time was 1 and 0.9 nsec, respectively.
