Abstract
We developed a laser-plasma source based on cryogenic targets that generates continuous repetitive X-ray pulses . This source has a translating substrate system with a closed cryostat of He gas that can continuously supply solid Ar, Kr and Xe targets . The plasma emissions showed stable, continuous output power at frequencies of 1–10 Hz. At a laser intensity of 5 × 1012 W/cm2, the Ar plasma emitted strongly in the water window region (2.3–4.4 nm), and its average X-ray power was 140 mW at a laser power of 1 W.
