There is a number of experiments around the world using liquid xenon as detector medium. These include search for lepton number violating muon decay, dark matter searches, neutrino physics and double beta decay. Although the energy ranges of interest of these experiment are different, they have very much in common from the detection point of view. Our team is focused on the processes triggered by particle interaction with liquid xenon and associated technologies, focusing on giving significant contributions to the future generation of liquid xenon detectors. The scope of our activities encompasses all the electronic, optical and molecular processes generated in a single- or double-phase liquid xenon detector due to particle interactions in the medium.
For the next few years our focus will be on studying satellite signals in liquid xenon double phase electroluminescence TPCs in the framework of the recently funded project for participation in the RD51 Collaboration at CERN.
