Abstract

Factors affecting the stability of gadolinium- and neodymium-loaded liquid organic scintillators intended for use in large-scale experimental facilities for neutrino physics and astrophysics are examined. The effect of composition (type and structural formula of gadolinium and neodymium compounds) on the optical properties of such scintillators is analyzed. It is shown that the oxidation of alkylbenzenes is one of the reasons for the degradation (decrease in transparency) of the scintillators. Gadolinium and neodymium compounds may be catalysts for the oxidation processes.

含and和钕的液态有机闪烁体

摘要

研究了影响中微子物理学和天体物理学的大型实验设施中使用的负载lin和钕的液态有机闪烁体稳定性的因素。分析了组成（（和钕化合物的类型和结构式）对这种闪烁体光学特性的影响。结果表明，烷基苯的氧化是闪烁体降解（透明度降低）的原因之一。d和钕化合物可能是氧化过程的催化剂。
