Debris-free single-line laser-plasma x-ray source for microscopy
نویسندگان
چکیده
A debris-free, narrow-bandwidth, single-line laser-plasma soft x-ray source has been developed suitable for water-window microscopy using zone-plate optics. The 10 Hz table-top source utilizes microscopic ammonium hydroxide droplets as target. The N VI emission at l52.88 nm is ;1310 photons/~sr pulse!. As an alternative to ammonium hydroxide, it is demonstrated that urea dissolved in water also produces strong emission from nitrogen ions, thereby extending the applicability of the droplet x-ray source to a new range of target materials. © 1995 American Institute of Physics.

A new target system based on a continuous cryogenic liquid jet for debris-free laser-plasma soft x-ray generation is described. The system is experimentally evaluated with liquid nitrogen as target material. With this target the photon flux is 4.5310 photons/~sr3pulse! from the l52.88 nm N VI line. Brightness and stability are also investigated for this table-top soft x-ray microscope source. T...

As a mass limited target the water droplet laser plasma source has been shown to have many attractive features as a continuous, almost debris-free source for extreme ultraviolet (EUV) and X-ray applications. Through a dual experimental and theoretical study, we analyze the interaction physics between the laser light and the target. The hydrodynamic laser plasma simulation code, Medusa103 is use...
متن کاملTarget optimization of a water-window liquid-jet laser–plasma source
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 l53.37 nm C VI x-ray flux and the debris deposition rates are presented as function of the jet diameter. It is shown that the effective carbon debris deposition is more than ...
متن کاملDroplet target for low-debris laser-plasma soft X-ray generation
Laser-produced plasma (LPP) is an attractive table-top soft X-ray source for, e.g., microscopy or lithography, due to its small size, high brightness and high spatial stability [ 1 ] _ However, the conventional LPP on solid targets produces debris which may destroy or coat fragile X-ray components, such as windows or zone plates, positioned close to the plasma. Unfortunately, increasing the dis...
