A liquid organic TPC for monitoring nuclear waste repositories — Malte Göttsche1, Thomas Radermacher2, Stefan Roth2, and •Georg Schwefer1 — 1RWTH Aachen University - AICES Graduate School, Aachen, Germany — 2RWTH Aachen University - Physics Institute III B, Aachen, Germany
In neutrino physics, the low energy region below 5 MeV is of great interest, e.g. for the investigation of solar neutrinos and geo-neutrinos. This energy regime is also crucial for the newly envisioned application of monitoring underground repositories of radioactive waste by measuring the antineutrino emissions produced by β-decaying isotopes present in the waste. To this end, we are investigating a detector design using a time projection chamber (TPC) based on a room-temperature organic liquid for precision measurements of low energy neutrinos. In this presentation, the results from first simulation studies on the reconstruction of low-energy antineutrinos in a liquid organic TPC and on the expected signal rates from nuclear waste repositories are discussed.
