Outline of Final Research Achievements

For in-situ measurement of a high-energy electron beam created by ultra intense laser light inside a solid material, Cherenkov emission from the electron beam was investigated using a prism target which can be a spectrometer for the Cherenkov light. Materials with different refractivity were used such as glass (n=1.5), high-refractive glass (n=2.0), and silicon crystal (n=3.5). We successfully obtained the electrons in a broad energy range by extending the observing wavelengths of Cherenkov emissions from visible to middle infrared.
