Drift Velocity of Electrons in Nitrogen?Argon Mixtures

Abstract

Electron-drift velocities have been measured in mixtures of 0�1 %, 1 % and 5 % nitrogen in argon at 293 K. A modification of the drift-tube system, which provides semi-automatic control and data collection, is described. Agreement with some previous work is very good. The uncertainty of the present measurements is estimated to be less than 1 %.
