Liquid-jet/liquid droplet initiated plasma discharge for generating useful plasma radiation

Abstract

Plasma discharge sources for generating emissions in the VUV, EUV and X-ray spectral regions. Embodiments can include running a current through liquid jet streams within space to initiate plasma discharges. Additional embodiments can include liquid droplets within the space to initiate plasma discharges. One embodiment can form a substantially cylindrical plasma sheath. Another embodiment can form a substantially conical plasma sheath. Another embodiment can form bright spherical light emission from a cross-over of linear expanding plasmas. All the embodiments can generate light emitting plasmas within a space by applying voltage to electrodes adjacent to the space. All the radiative emissions are characteristic of the materials comprising the liquid jet streams or liquid droplets.
