Оптическая и химическая стабильность жидкого сцинтиллятора детектора iDREAM на Калининской атомной электростанции

Optical and chemical stability studies were performed for a Gd-doped liquid scintillator, synthesized for use in a prototype of the industrial reactor antineutrino detector iDREAM. It is shown that 1 m^{3} scintillator solution remains stable for two years of observations under conditions of keeping the temperature below ~20 ⁰С and preventing its contact with air.
