Outline of Final Research Achievements |
As optical components in soft X-ray region, such as Wolter-type mirror and/or Freznel zone-plate lens, have a small numerical aperture, it is difficult to get a bright and high resolution images in microscope system. The purpose of this research is to develop the new focusing optical element to get X-ray spot of an atomic order using a quasicrystal pattern. In this research we simulate the focusing effect of quasicrystal optical element with computer. We also made quasicrystal pattern by using a focused ion beam equipment and performed an irradiation experiment using a synchrotron facility. We clarified the principle of focusing effect of quasicrystal optical elements and showed the possibility to confine the X-ray upto the wavelength level in principle.
