Practical Application of HgI_2 Detectors to a Space-Flight Scanning Electron-Microscope
Chicago
Abstract
Mercuric iodide X-ray detectors have been undergoing tests in a prototype scanning electron microscope system being developed for unmanned space-flight. The detector program has met with considerable success, although not all goals have yet been met. This success has been the result of carefully addressing the issues of geometric configuration in the SEM, compact packaging that includes separate thermoelectric coolers for the detector and FET, X-ray transparent hermetic encapsulation and electrical contacts, and a clean vacuum environment.
