Abstract： |
The present invention belongs to the field of radiation detection technology. The radiation imaging array solid detector includes flash crystal of cesium iodide or cadmium tungstate, photodiode coupled with the flash crystal and casing holding the flash crystal and the photodiode. The casing consists of metal cover plate, metal bottom plate, front end cover, back end cover and two side plates. The metal cover plate is provided with several slots for heavy metal partitions to set in and to separate flash crystals to form several solid detectors. The photodiode is led out through insulators penetrating the metal bottom plate and rubber pad, and there are rubber pads for insulation between different parts. Compared with available technology, the present invention has high detection efficiency, simple production process, less dead area and other advantages. |
