Laboratory Evaluation Of A High-Resolution X-Ray Microscope

High spatial resolution X-ray microscopes are being developed for autoradiography of laser fusion reactions and for relay optics, linking an X-ray telescope to focal plane instrumentation such as a photoelectric image detector or a spectrometer. The grazing-incidence optics consist of confocal axisymmetric ellipsoid and hyperboloid pairs. In both fields of application, high spatial resolution is required. The achievement of high spatial resolution involves meeting exacting tolerances on the figure and smoothness of the reflecting surfaces. The performance of a set of optics with 10X magnification has been evaluated in laboratory X-ray testing. The tests consist primarily of imaging various targets illuminated with soft X-rays, and recording the images on photographic film. In this paper we present the first results of the testing which show that resolu-tion of 1-2 Am has been achieved and that the reflection efficiency of the instrument is nearly 100 percent. We include information on the depth of focus and field of view.
