【 摘 要 】

Unresolved transition array (UTA) is scalable to shorter wavelengths, and we demonstrate a table-top broadband emission "water window" soft x-ray source based on laser-produced plasmas. Resonance emission from multiply charged ions merges to produce intense UTAs in the 2 to 4 nm region, extending below the carbon K edge (4.37 nm). An outline of a microscope design for single-shot live cell imaging is proposed based on a bismuth (Bi) plasma UTA source, coupled to multilayer mirror optics.
