Radioactive source measurements in a liquid xenon time projection chamber

Double beta decay is a rare nuclear process that can occur in two different modes. The first is known as the two-neutrino double beta decay, which is a second-order weak interaction process and has already been observed in several nuclei. The second one is called neutrino less double beta decay. This is a yet-to-be observed lepton number violating process, which can only be described by new physics, not included in the current standard model that describes elementary particles and their interactions. One attractive case for such studies is the double beta decay of 136Xe to 136Ba. Currently there are several international projects under development that aim to observe 136Xe neutrino less double beta decay. This project aims to contribute to such research with a study of charge-collection energy resolution, with radioactive source measurements in a liquid xenon time projection chamber (TPC).
