Abstract

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 ti, are given as a function of the electric field strength in the range 0.5 kV/cm less than or equal to/E/ less than or equal to 12.6 kV/cm and the temperature in the range 87 K less than or equal to T less than or equal to 94 K. A global parametrization of nu(d)(/E/, T) has been fitted to the data. A temperature dependence of the electron drift velocity is observed, with a mean value of Delta nu(d)/(Delta T nu(d)) = ( - 1.72 + 0.08)%/K in the range of 87-94 K. (C) 2000 Elsevier Science B.V.
