Abstract

Abstract The results of studies on increasing the radiation hardness of detectors based on organic plastic scintillators for the existing and new setups for experiments in physics of high energy particles are presented. The research was conducted at the Laboratory of High Energy Physics of the Joint Institute for Nuclear Research (JINR) during 2012–2021. Scintillator samples of various types were irradiated by radioactive gamma and neutron sources to high absorbed doses and low levels of a dose rate. Methods for increasing radiation hardness have been improved over a span of ten years. They benefited from the development of new compact photodetectors capable of registering individual light quanta.
