Abstract
A new large area detector of high-energy x-ray and b-radiation has been designed and studied. The design includes wedge-shaped light transducers. A composite material based on small crystalline ZnSe(Te) was applied onto the wide surface of light transducer. This design ensures optimum light collection from large sensitive surface onto the output window of much smaller size. An experimental specimen has been prepared, which showed β-sensitivity Cβ=5.5 cm2. The spectrograms of a 90Sr+90Y β-source obtained with the specimen under study make it possible to evaluate the age of the source by the ratio of low- and high-energy regions of the spectrum. Other designs are proposed for application of large-area detectors possessing wedge-shaped light transducers as elements of assembled constructions for high efficiency detectors operating under flow conditions.
