Operation of a Liquid Argon Time Projection Chamber
For the first time, the operation of a three-dimensional liquid argon time projection chamber has been demonstrated. This was accomplished in a 50 liter test detector using a readout plane with a woven structure etched on a PC-board.
A liquid argon TPC
Abstract Three dimensional particle tracking and a new purification technique based on electrical discharge in the liquid were successfully tested in a 15 1 LAr TPC.
The mobility of excess electrons in compressed liquid methane
Abstract The mobility of excess electrons in liquid methane has been measured as a function of temperature between 175 K and 220 K at an applied pressure of 5.5 × 106 Pa. A maximum in the mobility at 186 K and in addition a pronounced minimum at 200 K have been found.
