Abstract
The XM-1 soft x-ray microscope utilizes bending-magnet radiation from the Advanced Light Source in Berkeley, CA. This radiation is collected by a `large' (9 mm diameter) fresnel condenser zone plate which projects light through a pinhole and illuminates the sample. The radiation transmitted through the sample is then focused and magnified by a high-precision objective micro zone plate and recorded by a soft x-ray CCD camera. Our condenser zone plate and pinhole combination serves ad our adjustable monochromator for selecting the desired photon energy, giving us a (lambda) /(Delta) (lambda) of 700. This moderate spectral resolution allows for spectroscopic imaging with XM-1, including samples of magnetic materials with contrast provided by magnetic circular dichroism. Our user-friendly software programs allow for frequent utilization of complex image processing techniques.
