Cryogenic liquid-jet target for debris-free laser-plasma soft x-ray generation
نویسندگان
چکیده
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. The possibility to utilize other cryogenic liquids such as neon, argon, and xenon and, thus, making the system interesting for short-wavelength lithography applications, is also discussed. © 1998 American Institute of Physics. @S0034-6748~98!02506-4#

Liquid-jet target for laser-plasma soft x-ray generation
We describe a new liquid-target system for low-debris laser-plasma soft x-ray sources. The system is based on a microscopic liquid jet and is experimentally evaluated for 0.7–1 keV proximity lithography and water-window x-ray microscopy applications. Compared to an existing liquid-droplet target, this target system has the same low debris emission, high x-ray photon flux, and narrow spectral ba...
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 ...

We describe a method to fabricate tapered glass nozzles suitable for liquid-jet-target generation in laser-plasma soft x-ray and extreme ultraviolet sources. In the method, a tapered nozzle is formed as an integral part of a flexible capillary glass tubing. The method makes use of inert materials, extending the possible choice of target liquids compared to current nozzles. It also provides flex...
متن کاملDebris eliminatio in a droplet-target Baser-plasma soft x-ray source
A tabletop high-brightness line-emitting laser-plasma soft x-ray source utilizing single microscopic droplets as target is shown to produce several orders of magnitude less debris than conventional-target sources. Quantitative measurements of debris deposition rates and x-ray flux at different directions around the droplet plasma are presented. With ethanol droplets and a 10 HZ, 70 m.l/pulse la...

A compact, high-brightness and practically debris-free laser-plasma soft x-ray source for proximity x-ray lithography is described. The target of the source is small liquid fluorocarbon droplets injected into vacuum with a piezoelectrically vibrated nozzle. Emission from heliumand hydrogenlike fluorine in the 1.2–1.7 nm wavelength range was determined to ;2310 photons/~sr-pulse!, which correspo...
