Tellurium-loaded organic scintillators

Abstract

The R&D results of new tellurium-loaded liquid and plastic scintillators (TeLS and TePS) for the experiments on the search for neutrinoless double beta decay are presented. Linear alkylbenzene and polystyrene are used as a scintillation base for TeLS and TePS, respectively. Diphenyltellurium di-2-ethylhexanoate and a complex compound of diphenyltellurium oxide and di-(2-ethylhexyl)phosphoric acid are proposed as tellurium-containing additives. The transparency, light yield and long-term stability of the organic scintillators are discussed.
