Abstract :
A facility for high precision measurements of the transport parameters of electrons in gases has been built and operated. Two UV lasers and a radioactive source have been used to induce ionization in a gas volume where a uniform electric field is maintained. Drifting electrons are collected by a proportional wire. The details of the experimental apparatus are given together with some measurements of drift velocities in helium-isobutane and helium-methane gas mixtures.
