Spiral Zone Plate Microscopy

Printer-friendly versionPrinter-friendly versionPDF versionPDF version

Spiral zone plate (SZP) microscopy has been demonstrated at the coherent soft x-ray test station. Images of a gold pinhole were taken using a regular zone plate, charge 1 SZP, and charge 2 SZP. Edge enhancement as expected is seen in the cases of the SZP images.
