Method and apparatus for fabricating mercuric iodide polycrystalline films for digital radiography

摘要

A method is provided for fabricating in a thermal evaporation system a polycrystalline film capable of directly detecting radiation. Source material is placed in a container, and the container is evacuated to create a vacuum within the container. The source material is heated to evaporate the source material for depositing on a substrate. The polycrystalline film is used in as deposited form to detect the radiation.
