Annulus-sector-element coded Gabor zone plate at the x-ray wavelength

Laboratory arrangement for soft x-ray zone plate efficiency measurements.

We demonstrate a laboratory-scale arrangement for rapid and accurate measurements of the absolute and local efficiency of soft x-ray micro zone plates in the water window. This in-house instrument is based on a single-line lambda = 2.88 nm liquid-jet laser-plasma source. Measurements are performed by a simultaneous comparison of first diffraction-order photon flux with the flux in a calibrated ...

Towards 10-nm Soft X-Ray Zone Plate Fabrication

In this paper the latest efforts to improve our nanofabrication process for soft x-ray zone plates is presented. The resolving power, which is proportional to the smallest outermost zone width of the zone plate, is increased by introducing cold development of the electron beam resist that is used for the patterning. With this process we have fabricated Ni zone plates with 13-nm outermost zone a...

Application of Wavelength Dispersive X-Ray Spectroscopy in X-Ray Trace Element Analytical Techniques

Wavelength-dispersive spectrometer for X-ray microfluorescence analysis at the X-ray microscopy beamline ID21 (ESRF)

The development of a wavelength-dispersive spectrometer for microfluorescence analysis at the X-ray Microscopy ID21 beamline of the European Synchrotron Radiation Facility (ESRF) is reported. The spectrometer is based on a polycapillary optic for X-ray fluorescence collection and is operated in a flat-crystal geometry. The design considerations as well as operation characteristics of the spectr...
