Electron drift in a large scale solid xenon

A study of charge drift in a large scale optically transparent solid xenon is reported. A pulsed high power xenon light source is used to liberate electrons from a photocathode. The drift speeds of the electrons are measured using a 8.7\,cm long electrode in both the liquid and solid phase of xenon. In the liquid phase (163\,K), the drift speed is 0.193 $\pm$ 0.003 cm/$μ$s while the drift speed in the solid phase (157\,K) is 0.397 $\pm$ 0.006 cm/$μ$s at 900 V/cm over 8.0\,cm of uniform electric fields. Therefore, it is demonstrated that a factor two faster electron drift speed in solid phase xenon compared to that in liquid in a large scale solid xenon.
