DISCO: A hybrid Cherenkov Scintillation detection experiment for WbLS — •Amala Augusthy1, Manuel Böhles1, Noah Goehlke1, Daniele Guffanti2, Benedict Kaiser3, Tobias Lachenmaier3, and Michael Wurm1 — 1JGU Mainz, Institute for Physics and EC PRISMA+ — 2University of Milano-Bicocca & INFN Milano-Bicocca — 3Institute of Physics, University of Tübingen
Water based liquid scintillator (WbLS) is a novel detection medium capable of separating Cherenkov and scintillation components of a signal. The ability to separate the two light components will enable one to construct large low-threshold detectors with directional reconstruction capabilities. DISCO is a lab-scale experiment built to demonstrate such a separation and characterize WbLS. It uses muons as test particles to characterize detection media. It comprises of three main components: an external muon tracker, a test cell, and a light detection system. The test cell can be filled with water, liquid scintillator, or WbLS. The light detection system consists of 16 fast 1-inch PMTs with sub-nanosecond resolution. There is also a provision to include a LAPPD in the near future. This talk discusses the experimental set-up of DISCO and a preliminary tracking algorithm to evaluate the hit patterns produced by the muons on the PMTs. This project is supported by the DFG Graduate School GRK 2796: Particle Detectors.
