A simple photocathode for electron injection into high‐density gas is described. Relatively large electronic current pulses have been obtained by using a commerical low‐power xenon flash lamp. The photocathode efficiency has been studied as a function of the metal film thickness. The device has been used in swarm experiments at pressures up to 10 MPa in the temperature range 40–300 K.

Abstract
A simple photocathode for electron injection into high‐density gas is described. Relatively large electronic current pulses have been obtained by using a commerical low‐power xenon flash lamp. The photocathode efficiency has been studied as a function of the metal film thickness. The device has been used in swarm experiments at pressures up to 10 MPa in the temperature range 40–300 K.File in questo prodotto:
