A Measurement of the Drift Velocity of Electrons in the Electrical Field in Argon‐Alcohol Mixtures

摘要

The drift velocity of electrons in an electric field in argon and alcohol mixtures has been measured. The measurement has been taken observing on the screen of a triggered sweep oscillograph the rise time of pulses as given by α‐particles in an ionization chamber. The results give, for the 10 percent mixture, a behavior of the w(E/p) function, of the w=aE/p type up to E/p=2 v cm-1 mm Hg-1 values, and of the w=const type for larger values of E/p. Measurements at 0.5 and 5 percent alcohol concentrations are also reported.
