X-ray grating interferometry with a liquid-metal-jet source
T Thüring, T Zhou, U Lundström, A Burvall… - Applied Physics …, 2013 - pubs.aip.org
A liquid-metal-jet X-ray tube is used in an X-ray phase-contrast microscope based on a
Talbot type grating interferometer. With a focal spot size in the range of a few microns and a
photon flux of∼ 10 12 photons/s× sr, the brightness of such a source is approximately one
order of magnitude higher than for a conventional microfocus source. For comparison, a
standard microfocus source was used with the same grating interferometer, showing
significantly increased visibility for the liquid-metal-jet arrangement. Together with the …
