In-operando Three-Dimensional Measurement of Quantum State in the Practical Devices Using High-energy X-ray Compton Scattering Spectroscopy
Abstract
Compton scattering is one of the most promising probes which allow us for non-destructive measurement to the practical devices because it uses high-energy X-rays with a high penetration power. By using high-energy X-rays, the Compton scattering enables us to directly measure the light-elements like Li atom. Moreover, a Compton profile, so-called Compton scattered X-ray energy spectrum, directly links to wavefunction of the electrons. In this paper, we demonstrate unique quantitation method of Li ion distribution in a Li ion battery, and temperature distribution in a combustion flame. Our technique opens a novel analyzing pathway for developing the advanced practical devices.
