This cryogenic muon veto prototype is being operated within a customized copper holder on top of the still stage of the NUCLEUS cryostat and thermally coupled to a temperature of T\(_{still}\)\(\sim \)850mK. Since the muon rate will decrease the further down you go, we put the detectors in a subway station to measure how far underground we were.. The timing of the muon coincidences will be governed by the slow rise time of \({\mathcal {O}}\)(100\(\mu \)s) of the cryogenic target neutrino detectors. 2 We report upon the performance of an analog hadron calorimeter prototype, where plastic scintillator tiles are read out with wavelength-shifting fibers coupled to avalanche photodiodes. Meth. BC-404 can also be used in fast-counting applications. The highly reliable and direct detection of radioactive cesium has gained potential interest due to in-situ detection and monitoring in environments. By operating the disk-shape scintillator in a threefold coincidence with two external scintillator panels sandwiching it from top and from bottom, the charge spectrum can be restricted to exclusively muon events (Red). We will be working in a lab at the Wisconsin IceCube Particle Astrophysics Center (WiPAC) in Madison Wisconsin. A plastic scintillator-based muon tomography system with an integrated muon spectrometer, Nucl. This detector can be battery powered and is used in conjunction with the provided software.
