CsI: The x-ray detector which possesses Tl conversion layer

摘要

The x-ray detector has the conversion layer which converts X radiation to optical radiation. Optical receptible element is the especially photodiode, the electric information is obtained from the optical radiation which absorbs light with optical receptible element. As for conversion layer, the iodide cesium where thallium was filled (CsI: Tl) we include, this thallium fill iodide cesium super high purity is the thing, the fill level of Tl makes inside the range 0.25 - 1.00at%.
