Research Abstract

A monitor of surface modification of tungsten that is an important candidate among plasma-facing materials for a fusion reactor has been succeeded using spectroscopic methods such as optical reflectivity measurement and ellipsometry. Spectroscopic measurement of plasma near surface of a sample revealed excitation states of recycling neutral hydrogen isotopes. And also deuterium absorption properties of samples with helium bubbles and a deposited layer were brought out.
