Irradiation uniformity measurement of laser fusion pellets by an X-ray imaging method

H Honda, H Nishimura, S Miyamoto, M Nakai, K Mima1997年Fusion Engineering and DesignIF 1.7出版社

AbstractTime integrated X-ray emission images at an energy range of 1.8–3.6 keV were obtained to evaluate laser irradiation nonuniformity on fusion pellets. The experimental results were analyzed with a simple illumination calculation. A positive correlation was found between the nonuniformity obtained from the measured X-ray emission intensity and that from the calculated laser irradiation intensity, although the absolute values of the nonuniformities are discrepant.
