W1-11 Neutrinoless Double Beta Decay (DNP/PPD) | Double désintégration bêta sans neutrino (DPN/PPD)
- Thomas Brunner (McGill University)
The EXO-200 and nEXO Collaborations are searching for the neutrinoless double beta (0vbb) decay of 136-Xe using time projection chambers (TPCs) filled with enriched liquid xenon.
EXO-200 has completed phase II operations in December 2018 with upgraded hardware. Highlights of EXO-200 contributions and final results will be presented.
nEXO is a tonne-scale 0?vbb decay search based on the...
During the last decade, Silicon Photo-Multipliers (SiPMs) have emerged as a compelling photo-sensor solution. Low-voltage power, optimal operation at cryogenic temperature, and low radioactivity levels with negligible gain fluctuations are among the advantages of SiPMs over the widely used PhotoMultipliers Tubes (PMTs). Accordingly, large-scale low-background cryogenic experiments, such as the...
The EXO-200 Collaboration is searching for neutrinoless double beta decay (0vBB) using a liquid xenon time projection chamber, enriched in 136Xe. EXO-200 successfully finished two phases of data taking in December 2018. Now the collaboration is working towards a 0vBB search using the complete data set, with better energy resolution and increased discrimination of backgrounds, that is expected...
Silicon Photo-Multipliers (SiPMs) have emerged as a compelling photo-sensor solution over the course of the last decade. In contrast to the widely used Photo-Multipliers Tubes (PMTs), SiPMs have high single Photon Detection Efficiency (PDE) with negligible gain fluctuations, are low-voltage powered, optimal for operation at cryogenic temperatures, and have low radioactivity levels. For these...
