Drift Velocities of Electrons in Cesium

Abstract

The drift velocities of electrons in cesium vapor have been measured for $\frac{E}{p_0}$ values between 0.8 and 20V/cm×Torr at temperatures between 566 and 725°K. The data were obtained from electron transit-time measurements using a pulsed-discharge technique. By obtaining differential transit times, injection and endeffect errors were minimized. The general variation of the drift velocity with $\frac{E}{p_0}$ was found to be comparable to that previously observed for some of the noble gases.
