NSLS-II Seminar

"Optics, Sources and Systems for Laboratory X-ray Micro- and Nano-Imaging"

Presented by Hans Hertz, Department of Applied Physics, Royal Inst. of Technology, Stockholm, Sweden

Thursday, September 16, 2010, 10:30 am — NSLS-II Seminar Room, Bldg. 817

Progress in laboratory-scale x-ray micro- and nano-imaging is reviewed. In the soft x-ray regime we demonstrate laboratory water-window microscopy with <25-nm-resolution, 3D microtomography of cryo-fixed biological samples, and aqueous-state imaging of environmental colloids. The progress relies heavily on our developments in diffractive optics, for resolution (13 nm Ni zone plates, compound zone plates), efficiency (Ni-Ge zone plates, now also at 13 nm) and for new contrast mechanisms (DIC and Zernike zone plates). In hard x-rays (10-30 kV) we discuss diffractive optics for high-brilliance synchrotron sources as well as phase-contrast x-ray imaging with few-µm detail based on a high-brightness laboratory electron-impact liquid-metal-jet-anode x-ray source.
