| Abstract(in English) | Energy dispersive X-ray spectroscopy (EDS) performed with a scanning transmission electron micro-scope (STEM) is now playing an important role for compositional analysis in various research fields such as nan-otechnology, material science and biotechnology. However, due to a low energy resolution of ～130 eV with a Si(Li) solid-state detector (SSD), generally used in a STEM-EDS, many spectral peaks are hard to separate. We are then developing a new STEM-EDS system with a superconducting transition-edge sensor (TES) microcalorimeter array to achieve a good energy resolution (< 10 eV) in wide-energy band (0.5 - 10 keV). We describe the design of 64-channel TES array prototype optimized for STEM-EDS and the result of the first X-ray irradiation test. |
