Drift velocity of free electrons in liquid argon

Creators

Description

A measurement of the drift velocity of free electrons in liquid argon has been performed. Free electrons have been produced by photoelectric effect using laser light in a so-called 'laser chamber'. The results on the drift velocity vd are given as a function of the electric field strength in the range 0.5 kV/cm≤|E|≤12.6 kV/cm and the temperature in the range 87 K≤T≤94 K. A global parametrization of vd(|E|,T) has been fitted to the data. A temperature dependence of the electron drift velocity is observed, with a mean value of Δvd/(ΔT vd)=(-1.72±0.08)%/K in the range of 87-94 K
