Transmission efficiency of high power density soft X-ray through capillary
Аннотация
In order to optimize the soft X-ray lens design,obtain high power density soft X-ray without other particles by combining it with plasma radiant point,experiments of measuring transmission efficiency with the power density range of 6×106～1.5×107 W/cm2 for the X-ray capillary on Qiangguang Ⅰ facility were carried out.The results show that,for the capillary of glass DM308,basically,the power density of the output soft X-ray from the capillary is linear with the power density of the incidence soft X-ray;when the power density of the incidence soft X-ray is 1.2×107 W/cm2,the average transmission efficiency is 16.3%.Based on the experiment results,soft X-ray lens were made,and power density 2.1×109 W/cm2 of soft X-ray without plasma fragment was obtained at the focal point.
