High-Brightness Sources and Light-Driven Interactions.
X-ray analysis/metrology rely heavily on the x-ray source brightness for resolution/exposure-time. Traditional x-ray tubes are limited by when the e-beam power-density melts the anode. The MetalJet overcomes this limitation by using a liquid anode.

We investigate the hydrodynamic properties of liquified-inert-gas jets in a vacuum with a special emphasis on their stability. Such jets have applications as targets for laser–plasma generation of soft-x-ray and extreme-ultraviolet (EUV) radiation.

We optimize the water-window x-ray flux and debris deposition for a liquid-jet laser plasma source by varying both the target diameter and the jet material. For two target liquids, methanol and ethanol, measurements of the λ=3.37 nm C VI x-ray flux

We have developed the first operative compact sub-visible-resolution x-ray microscope for the water-window region (λ = 2.3 - 4A nm). The microscope is based on a 100 Hz liquid-jet-target laser-plasma x-ray source, normal-incidence multilayer condens

The power and brightness of electron-impact micro-focus X-ray sources have long been limited by thermal damage in the anode. Here we describe a novel X-ray microfocus source based on a new anode concept, the liquid-metal-jet anode (MetalJet). The reg
