Abstract
An electron beam from an electron column instrument impinges on a target foil to produce a primary X-ray beam which, in turn, passes through a collimator to impinge on a specimen. The X-rays fluoresced from the specimen by the primary X-ray beam are detected by a solid state radiation detection device.
