Laser stimulated photocathode electron beam prober for 15ps resolution waveform measurements

Abstract

In order to overcome the bandwidth limitations of conventional electron beam probe systems a new instrument was developed which uses laser-stimulated photoemission to generate 15ps electron sampling pulses. Results from probing an ECL communication circuit with rise times of 100ps and stage-to-stage delays of less than 50ps demonstrates a typical application. © 1994.
