60-liter liquid xenon time projection chamber (LXe-TPC) for study of radiative pion decay

We present measurements on purity and long-term stability of a 60 l liquid Xenon TPC, showing electron lifetimes in the liquid higher than some milliseconds for a period of one month. The electron lifetime is measured with a monitor chamber inside the TPC. The method is based on the measurement of the number of electrons extracted from a photocathode and collected on the anode after the drift through an electric field. We also report on preliminary results of the calibration of the TPC with gamma-ray sources.© (1994) COPYRIGHT SPIE--The International Society for Optical Engineering.
