| Outline of Final Research Achievements |
To create a future system of a table top "water window" soft X-ray microscope to observe organelles in living cells, we developed a small prototype light source system using focusing glass capillary, because glass has advantage of high reflectivity for wavelength region from 2.28 to 4.36 nm. The light intensity emitted from the discharge produced plasma assisted by pulsed laser, is measured with our small calibrated detector. In typical case of the discharge voltage 6kV with the single capillary, the electric discharge current is estimated approximately 6A with 0.01ms pulse, and the electric discharge energy is evaluated about 360mJ. However, the light intensity is not enough to observe organelles in living cells. We will reconstruct the "water window" soft X-ray source system using focusing polycapillary optics.
