Abstract
An electron microscope including a vacuum chamber for containing a specimen to be analyzed, an optics column, including an electron source and a final probe forming lens, for focusing electrons emitted from the electron source, a specimen stage positioned in the vacuum chamber under the probe forming lens for holding the specimen, and an x-ray detector positioned within the vacuum chamber. The x-ray detector includes an x-ray sensitive solid-state sensor and a mechanical support system for supporting and positioning the detector, including the sensor, within the vacuum chamber. The entirety of the mechanical support system is contained within the vacuum chamber. Multiple detectors of different types may be supported within the vacuum chamber on the mechanical support system. The mechanical support system may also include at least one thermoelectric cooler element for thermo-electrically cooling the x-ray sensors.
