Drift Velocities of Electrons in Some Commonly Used Counting Gases

Abstract

The original method of Stevenson has been used to develop an apparatus capable of yielding high precision for the drift velocities of electrons moving in an electric field. Measurements have been made of the electron drift velocity in argon, nitrogen, methane, carbon dioxide, ethylene, cyclopropane, and a few mixtures of some of these gases. The results for argon and nitrogen agree with those of Nielsen.
