Soft x-ray generation using CNT based liquid hybrid target

Summary form only given. In order to image soft biological tissues that are consisted of living animal or plants, water window (2.1-4.4 nm) region of soft X-ray is generally required. However, conventional X-ray source that is based on tungsten filament tube generally produces hard X-ray. In order to solve this problem, laser based soft X-ray sources have been studied recently. In this technique solid metal or liquid-jet target has been generally applied. However, debris problem was issued for the former and small intensity of the generated soft X-ray was the problem for the latter. In this research, liquid target, which is added with carbon nanotubes (CNTs) or other metal nanopowders, was proposed as new targets for laser based soft X-ray generation. Detailed descriptions of the experimental method and results were presented in this study
