Abstract
An apparatus for testing infrared detector response to ionizing radiation within an infrared shielded environment includes a cryostat having an aperture which is positioned adjacent to a scanning electron microscope (SEM). The SEM generates an electron beam which propagates through the aperture and is absorbed by a foil positioned adjacent the detector. The interaction of the electron beam with the foil produces X-rays which irradiate the detector. Instruments electrically coupled to the detector record and display the detector response.
