Organic Scintillators

Studies of the relative Light output and optical transmission of organic composite scintillators with different grain sizes were performed. The research results showed that for samples with grains 0.06…0.3 mm in size, in contrast to the samples with larger grains, the relative light output and optical transmission are lower.

Decay Times

The source of the delayed fluorescence by triplet—triplet interactions is discussed as the basis of the technique of differentiating between particles of different specific ionizations. The variation in the relative intensity of delayed fluorescence (called the slow component of scintillation) is correlated with the type of ionizing radiation. The decay times of the prompt and slow components do not depend upon the type of ionizing particle. The slow component in liquid scintillator solutions free of dissolved gases (especially oxygen) has a decay time of about 250 × 10−9 sec. Liquid scintillator solutions with pulse shape discrimination properties have been used to measure neutrons (proton recoils) in the presence of gamma rays (Compton scattered electrons). They have also been demonstrated as able to measure the relative activities of alpha particles and fission fragments from a fission source in the presence of gamma and beta background.

AbstractThe experiment SONG (SOlar Neutron and Gamma rays) for the low altitude satellite CORONAS-I is described. The instrument is capable to provide gamma-ray line and continuum detection in the energy range 0.1 – 100 MeV as well as detection of neutrons with energies above 30 MeV. As a by-product, the electrons in the range 11 – 108 MeV will be measured too. The pulse shape discrimination technique (PSD) is used.
