Development of a new tellurium loaded liquid scintillator based on linear alkylbenzene

The R&D results of new tellurium loaded liquid scintillators based on linear alkylbenzene are presented in this work. For the first time, diphenyltellurium dicarboxylates (dipivalate, diisovalerate, di-2-ethylhexanoate) are used as tellurium-containing additives. The optical properties (transparency, light yield) of the scintillator have been studied depending on the tellurium concentration, comprehensive studies have been carried out to optimize the composition of the scintillator, the effect of the secondary scintillation solvent on the light yield has been studied, and the long-term stability of Te-LS has been finally established.
