Hybrid scintillator detectors aim at the simultaneous detection of Cherenkov and scintillation light. SCHLYP (Scintillation CHerenkov Light Yield Prism) is a newly developed laboratory setup, used to distinguish Scintillation and Cherenkov light in scintillator samples. The setup uses the geometrical advantages of a hollow prism filled with various scintillator samples as a detector, equipped with three ultra-fast photomultipliers, on each side. Photons from a close-by 137Cs source create a signal by Compton scattering in the scintillator. Using a secondary inorganic scintillator detector, recoil photons are selected to be aligned with the prism geometry, so that two of the PMTs detect both Cherenkov and Scintillation light, while the third PMT is only able to detect scintillation light. The samples being investigated range from slow scintillators to water-based liquid scintillators. In this talk the improved setup and the analysis of the phase II data will be presented.
