Experimental Determination of the Drift Velocity of Low-Energy Electrons in Ar, N2, CO2, Several Ar–N2 Mixtures, and Several Ar–CO2 Mixtures

An experimental determination of the drift velocity of low-energy electrons in argon, nitrogen, carbon dioxide, several mixtures of argon and nitrogen, and several mixtures of argon and carbon dioxide used a pulsed ionization chamber with alpha particles as the source of ionization. The experimental data for the single gases serve to verify the experimental technique. The results and a detailed estimation of the possible experimental errors are presented.
