Opaque Scintillator for Neutrino PhysicsChristian Buck1, Benjamin Gramlich1, and •Stefan Schoppmann21Max-Planck- Institut für Kernphysik, Saupfercheckweg 1, 69117 Heidelberg, Germany — 2JGU Mainz, Exzellenzcluster PRISMA+, Detektorlabor, Staudingerweg 9, 55128 Mainz, Germany

A new scintillator system was developed based on admixtures of wax in organic scintillators. The opacity and viscosity of this gel-like material can be tuned by temperature adjustment and wax concentration. Whereas it is a colourless transparent liquid at temperatures above 40C, it has a milky wax structure below.

Due to its light confinement, the scintillator system is expected to exhibit unprecedented particle ID via the topology of energy depositions. Moreover, a high degree of metal loading is feasible.

In this presentation, the production and properties of such a scintillator as well as its advantages compared to transparent liquids are described.
