Cerium-doped lutetium silicate scintillation crystal radiation detector with exit surface cooperated with lens group

Abstract

The invention relates to a scintillation crystal radiation detector with a special exit surface cooperated with a lens group. A matched wide-angle and large-depth-of-field lens group is constructed; the scintillation light collecting efficiency of a light sensor is improved; the energy resolution is improved; matching with the emergent waveband of the scintillation crystal itself is considered inspecific parameter design; more scintillation light is focused and collected and then input to the light sensor; the shape of the exit surface of the scintillation crystal cooperated with the lens group is designed correspondingly to further improve the measuring efficiency and precision; and in particular, the detection performance for researching and developing a high-performance detector can befurther improved.

Description

technical field [0001] The present invention relates to the measurement of nuclear radiation or X-ray radiation, in particular to the measurement of X-ray radiation, γ-ray radiation, particle radiation or cosmic ray radiation, in particular to a scintillation detector in which the scintillator is a crystal in radiation intensity measurement. Background technique [0002] Radiation measurement has played an important role in many fields, such as nuclear power plant radiation measurement, continuous measurement of radiation dose at the measurement site; industrial and civil buildings, building decoration, production and manufacturing of building materials, radioactivity measurement of various building materials; Geological exploration, geological prospecting and mine radiation measurement; used for ray security inspection access doors, which can provide assistance for customs, airports, border inspections, and security inspections of important meeting places; radiation measurem...
