Cone – shell target<\/h2>\n
In order to realize efficient plasma heating with high speed ignition method, we have developed a cone – shell target. We were first in the world to have demonstrated plasma heating by fast ignition method using the cone-shell as target. Now this target is used as the standard.<\/p>\n

By irradiating the laser from the lateral hole, the inside of the target was uniformly heated, and light of a wavelength to be measured was subsequently irradiated from the front window, and the absorptance was calculated from the ratio with the back light. This experiment gave important knowledge in the development of extreme ultraviolet light sources for semiconductor manufacturing.<\/p>\n
