The new Alemnis HTME-1000 is specifically designed for Electron Backscatter Diffraction (EBSD) analysis of a heated sample up to 1000°C. It is not mountable on an Alemnis Standard Assembly (ASA) but is used freestanding in any SEM.
See this example of droplet formation of a Au thin film at 1000°C. The SEM chamber view confirms the efficiency of the shielding and minimal radiation at 1000°C. Thanks to Szilvia Kalácska and Amit Sharma at EMPA, Thun (Switzerland). See the HTME-1000 module here
