表題
ナノ美 : Your Next Electron Microscope
講演要旨
We are developing a public license hardware and software platform to build an electron microscope, the NanoMi [1,2]. NanoMi utilizes electrostatic optics making it easy to manufacture. The electron optics is modular with components placed either on a 5-inch diameter half pipe, or in a v-groove, at nearly arbitrary locations. Various electron-optical arrangements can be quickly explored and the electron optics is independent from its vacuum envelope.
The design targets are: acceleration voltage is 50 kV, to reduce cost and x-ray hazard; up to 10 nm spatial resolution in TEM, SEM and STEM mode and electron diffraction (ED) capability. A single Linux computer is used to control NanoMi over a digital IO board, and a Canon M50 digital camera used to collect images from a fluorescent screen.
