Ultra-high resolution & sensitivity electron spectrometer

Next-generation electron spectrometer, which simultaneously satisfies the trade-off between energy resolution and sensitivity while keeping the instrument compact.

Overview

　Electron spectroscopy is a method to study the electronic structure of matter by measuring the energy distribution of emitted electrons due to ionization caused by irradiation of energy ray such as a photon and an electron beam. Various types of electron spectrometers, such as time-of-flight and electrostatic analyzers, have been developed, depending on the electron energy range to be covered. Nevertheless, one may desire to have a next-generation spectrometer.

　This technology is based on a completely new principle, which enables one to have an ultra-high energy resolution that has never been achieved. Its application is very wide, since it can be employed for any energy electrons while providing high sensitivity and the ability to measure the angular distribution.
