Problems solved by technology

However, the equipment investment of chemical vapor deposition method CVD and vacuum sputtering method is very high
CVD and vacuum sputtering methods have slow film formation rate and low effective efficiency
The silicon dioxide SiO2 film formed by the vacuum sputtering method is not dense enough, and the water vapor penetration performance is not as good as that of bulk solid SiO2

Abstract

The invention proposes a sodium iodide or cesium iodide scintillator packing structure and the packing method thereof, wherein the packing method comprises the following steps: adhering the inner surface of a metal housing to the reflection layer; adhering the reflection layer to the sodium iodide or cesium iodide scintillator; placing seal glue at the threaded edges of the metal housing so that the seal glue is adhered to the outer surface of the metal housing; under a vacuum environment, pressing the optical coupling agent to the upper surface of the sodium iodide or cesium iodide scintillator layer to enhance the transmission rate of visible light; adhering the optical coupling agent to the lower surface of the reinforced glass layer wherein the circumference of the reinforced glass layer is all adhered to the seal glue and the seal glue is adhered to the metal housing. With the above method, the cost can be reduced; the seal performance, the light transmission rate and the light reflection rate can be increased; and the manufacturing cycle can be shortened.

Description

technical field [0001] The invention belongs to the technical field of nuclear radiation detection and inorganic luminescent materials, and relates to a method for improving the luminescence collection efficiency of cesium iodide-doped sodium CsI(Na) and sodium iodide-doped thallium NaI(Tl) crystals excited by gamma rays. In particular, it relates to a method for packaging radiation detectors based on CsI(Na) and NaI(Tl) crystals, a method for preparing gamma-ray pulsed radiation detection materials, and especially relates to a sodium iodide or cesium iodide scintillation body packaging structure.
