Description
Известно применение дл регистрации -излучени галогенных счетчиков и сцинтилл цконных счетчиков с монокристаллами антрацена, стильбена, с тонкими сло ми стильб на на подложках из оргстекла, со сцинтиллирующей пластмассой на основе полистирола с р-терфенилом. Галогенные счетчики имеют высокую эффективность регистрации р-излучени . но не регистрируют р-излучени малой энергии. Сцинтилл ционные счетчики, с iOнoкpиcтaJ;лами антрацена и стильбена нар ду с высокой эффективностью регисграции р-излучени имеют высокую чувствительность к v-фону. С уменьшением толщины кристаллов чувствительность к можно понизить , но одновременно падает эффективность регистрации р- злучени . Размеры монокристаллов ограничены по диаметру.It is known to use for the detection of -radiation of halogen counters and scintills of cone counters with anthracene single crystals, stilbene, with thin layers of stilb on plexiglas substrates, with polystyrene-based scintillating plastic with p-terphenyl. Halogen counters have high p-radiation detection efficiency. but do not register low-energy p-radiation. Scintillation counters, with iOnocrites; lamis of anthracene and stilbene, along with high efficiency of р-radiation recording, have high sensitivity to v-background. With a decrease in the thickness of the crystals, the sensitivity to can be reduced, but at the same time the efficiency of p-radiation detection decreases. The size of single crystals is limited in diameter.
Предлагаемый сцинтилл тор дл регистрации р-излучени па 7-фоне отличаетс тем, что дл увеличени конверсионной эффективности дл р-излучени малой и большой энергии, а также дл облегчени технологии изготовлени сцинтилл торов большого размера, он выполнен в виде тонкого цилиндра из сцинтиллирующей пластмассы. На пластмассу напыл етс стильбен (в вакууме) плотностью пор дка 15-20 MzlcM. Размеры сцинтилл тора можно мен ть по то.:1и;ине и nq диаметру.The proposed scintillor for detecting p-radiation on a 7-background is characterized in that in order to increase the conversion efficiency for low- and high-energy p-radiation, as well as to facilitate the technology of making large-sized scintillators, it is made in the form of a thin cylinder of scintillating plastic. Stilbene is sprayed onto plastic (in vacuum) with a density of about 15-20 MzlcM. The dimensions of the scintillator can be varied according to this: 1 and; yne and nq diameter.
Сочетание сцинтиллирующей пластмассы и тонкого сло стильбена позвол ет увеличить конверсионную эффективность сцинтилл тора к излучению больших и малых энергий, то есть эффективность преобразовани поглощенной энергии в световую. Через тонкие слои стильбена на оргстекле р-излучение больших энергий проходит с частичным превращением своей энергии в световую, остальна ее часть проходит, не задержива сь в тонких сло х. При использовании подложки дл тонких слоев стильбена из сцинтиллирующей пластмассы взамен оргстекла достигаетс возможность более полного превращени р-излучени боль1ПОЙ энергии в световую. Таким образом, при соответственно подобран-.The combination of scintillating plastics and a thin layer of stilbene makes it possible to increase the conversion efficiency of the scintillator to the radiation of high and low energies, i.e., the efficiency of conversion of the absorbed energy into light. Through thin layers of stilbene on plexiglass, high-energy p-radiation passes with a partial transformation of its energy into light, the rest of which passes, without being delayed in thin layers. When using a substrate for thin layers of stilbene from scintillating plastic instead of plexiglass, it is possible to more fully convert the p-radiation of large-scale energy into light. Thus, when appropriately matched.
