An improved measurement of electron-ion recombination in high-pressure xenon gas
An improved measurement of electron-ion recombination in high-pressure xenon gas
We report on results obtained with the NEXT-DEMO prototype of the NEXT-100 high-pressure xenon gas time projection chamber (TPC), exposed to an alpha decay calibration source. Compared to our previous measurements with alpha particles, an upgraded detector and improved analysis techniques have been used. We measure event-by-event correlated fluctuations between …
