Antineutrino Monitoring with Liquid Organic Time Projection Chambers — Johannes Bosse, Sarah Friedrich, Malte Göttsche, Helge Haveresch, •Thomas Radermacher, Stefan Roth, Georg Schwefer, and Hagen Weigel — RWTH Aachen University - Physics Institute III B, Aachen, Germany

For the first few hundreds of years the dominant radioactivity of nuclear waste comes from long-lived beta-decaying elements that are emitting antineutrinos in the low-energy region below 5 MeV. In a newly envisioned application for nuclear monitoring purposes, we want to use these antineutrinos to monitor the content of nuclear waste repositories. We are investigating a time projection chamber filled with an organic liquid aiming at full reconstruction of inverse beta decay events. In the low energy region, the direction of the neutron in IBD is strongly correlated to the direction of the incoming antineutrino. For this we study to which extend the neutron direction can be reconstructed by its first few elastic scatterings with the nuclei of the detector medium. This talk gives an overview on our project and the progress of our simulation studies.
