Electron Swarm Transport Through Low Pressure Noble Gases

Abstract

The electron drift velocity, the longitudinal diffusion coefficient and the electron ionisation coefficient have been measured in helium, neon, argon and krypton using the integrated voltage transient technique. Whilst the present data agree substantially with previous determinations at those values of E / N at which they overlap, the current work represents a marked extension of the range of E/N covered for We and NDL in most of the gases investigated.
