Tunable multilayer EUV/soft x-ray polarimeter
A tunable polarimeter using multilayer interference coatings as both reflection polarizer and transmission phase retarder is described. The portable device bolts onto existing chambers and its rotation axis is precisely aligned to the beam. The upstream transmission phase retarder is tunable by varying its incidence angle, and the downstream polarizer is tunable by translating a laterally grade...
متن کاملRegion-of-interest tomography for grating-based X-ray differential phase-contrast imaging.
We report numerical and experimental results demonstrating accurate region-of-interest computed tomography (CT) reconstruction based on differential phase-contrast projection (DPC) images. The approach removes the constraint of covering the entire sample within the field of view of the image detector. Particularly for biomedical applications, the presented DPC-CT region-of-interest approach wil...
متن کاملA slit grating spectrograph for quantitative soft x-ray spectroscopy
In this article we describe a new slit grating spectrograph which is based on an e-beam written 10 000 linepairs/mm freestanding transmission diffraction grating. In combination with a thinned, back-illuminated charge coupled device ~CCD!, the spectrograph allows for real-time spectroscopy of laser-produced plasma x-ray sources within the wavelength region l51–20 nm. Calibration of grating and ...
متن کاملEfficiency of a grazing-incidence off-plane grating in the soft-x-ray region.
Efficiency measurements of a grazing-incidence diffraction grating in the off-plane mount were performed using polarized synchrotron radiation. The grating had 5000 grooves/mm, an effective blaze angle of 14 degrees, and was gold coated. The efficiencies in the two polarization orientations (TM and TE) were measured in the 1.5-5.0 nm wavelength range and were compared with the efficiencies calc...
متن کاملOptimum driving a Z-pinch for soft X-Ray lasers
A capillary plasma z-pinch as an alternative active medium of soft X-Ray lasers was studied experimentally and theoretically. The theoretical analysis was based on the self consistent solution of the so called “snow plow” model. The dynamics of pinched plasma is determined by the capillary parameters and by the time dependence of electrical current passing through it. The current time dependenc...
