Abstract
Using the compact SR-ring `AURORA,' imaging performance of the soft x-ray microscope with a Schwarzschild objective were evaluated. The multilayer mirrors of the objective were designed at a wavelength of 135 angstroms with 41 layers of Mo/Si. X rays from the source were filtered with a Be membrane (1.5 micrometers thickness), and then focused on a sample with a paraboloidal condenser. Visible and UV light was removed with the Be filter, and hard x ray was removed with the condenser. X rays transmitted through the sample were imaged on a detector (micro-channel plate) with the Schwarzschild objective. The image was converted to visible light by a fluorescent screen, and monitored with a CCD camera. Magnified ratio was 200. Spatial resolution was evaluated as 0.3 - 0.45 micrometers from an edge response.
