One of the most promising approaches for the next generation of neutrino experiments is the realization of large hybrid Cherenkov/scintillation detectors made possible by recent innovations in photodetection technology and liquid scintillator chemistry.
This talk will focus on the development of such detector liquids with particularly slow light emission. Various attempts are currently underway, such as the use of special wavelength shifters or the use of blended multi-solvent cocktails. Several of these mixtures are compared with respect to their fundamental characteristics (scintillation efficiency, transparency, and time profile of light emission). In addition, the optimization of the admixture of wavelength shifters for a scintillator with particularly high light emission and pulse shape discrimination capability is presented. Newly developed purification methods based on column chromatography and fractional vacuum distillation for several candidate solvents are also discussed.
The work is supported by the Cluster of Excellence PRISMA+, the DFG Sonderforschungsbereich 1258 and the Bundesministerium für Bildung und Forschung (BMBF Verbundprojekt 05H2018: R&D Detectors and Scintillators).
