Cerium-doped lutetium silicate scintillation crystal radiation detector plated with antireflection film and special light emitting surface

Abstract

The invention relates to a scintillation crystal radiation detector plated with an antireflection film and a special light emitting surface. The conception of designing a film layer in a targeted manner is carried out aiming at a main emergent waveband of scintillation crystal, the difficulty that film research data is too large and difficult to analyze is overcome, an appropriate reflective filmlayer material is obtained, the adhesive force with crystals is good, the number of film layers is small and the implementation is easy, a special light-emitting surface design matched with a total reflection plating scheme is further provided, and the measurement efficiency and the measurement precision are correspondingly 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...
