| Outline of Final Research Achievements |
Using a polycapillary optics, we carried out a 3D design of a table-top soft X-ray microscope system for observation of living cells by focusing illumination in the "water window" wavelength area, and then we manufactured this prototype device. In our device, we use the soft X-rays emitted from the pulsed laser-produced plasma as a light source. Using a calibrated photodiode, we have measured the soft X-ray output transmitted through the polycapillary, and this result shows the intensity over 8,000,000 photons par shot from our pulsed laser-produced plasma. However, this intensity of the soft X-rays transmitted through a microscopic sample under atmospheric pressure is not sufficient to obtain an image with our CCD camera in this device. So, we use an additional paraboloid Ni mirror placed between the light source and polycapillary. We will develop imaging technology to realize the visualization of living cells with our tabletop soft X-ray device.
