Outline of Final Research Achievements

X-ray microscope is applied to the biological and life science. However, there is no demonstration of a compact, high brightness, single-shot water-window soft x-ray source. We propose the improvement of the high output flux for single-shot imaging in the water-window soft x-ray spectral region by a laser-produced bismath plasma.
In this study, we focus on three points: (A) development of the short pulse, high intensity carbon-deoxide laser as a middle infrared laser, (B) optimization of the output flux (number of photons) by analizing the measurement of the emission from highly charged heavy element ions and the radiation hydrodynamic simulation, and (C) optimization of the source output and optical system in the water-window soft x-ray microscope system.
