The Gottingen Scanning X-ray Microscope

The Gottingen scanning X-ray microscope was tested at the BESSY storage ring. Images with 0.1 micrometer resolution were obtained with 4.5 nanometer radiation delivered from the BESSY bending magnet. The number of spatial coherent photons in 1% bandwidth, which can be delivered by the used zone plate linear monochromator, was calculated to be 1.7 x 10 E 8 photons per second during this tests. The scanning time was less than 10 milliseconds per image point at a measured photon rate of more than 10 E 6 per second. The scanning time for one image was about 3 minutes.
