Metal-Loaded Liquid Scintillators for Neutrino Physics — Christian Buck, Benjamin Gramlich, Manfred Lindner, Christian Roca, and •Stefan Schoppmann — Max-Planck-Institut für Kernphysik, Saupfercheckweg 1, 69117 Heidelberg, Germany

Liquid scintillators have become a well established detection medium in the context of neutrino experiments. They offer good transparency and light yield while allowing for geometrical flexibility of the fiducial volume at low costs. By loading the scintillators with metal compounds, effectiveness of neutron detection can be highly increased making them suitable for applications e.g. in reactor neutrino physics.

Depending on the respective usage-case, additional scintillator properties such as particle identification and vertex resolution become beneficial. We report the development of scintillator in the context of the STEREO experiment which allows for good particle identification by exploiting light pulse shape discrimination. In addition we present the current status of a LAB-based scintillator aiming for improved spatial resolution.
