Abstract
The invention is directed to an arrangement for providing a reproducible target flow for the energy beam-induced generation of short-wavelength radiation. It is the object of the invention to find a novel possibility for providing a reproducibly supplied target flow for the generation of a plasma that emits short-wavelength radiation which ensures a high directional stability of the target flow over a large number of individual plasma generation process for any target materials under given process conditions. According to the invention, this object is met in that a nozzle protection device is provided in the interaction chamber between the target nozzle and the interaction point for the generation of the plasma, and the nozzle protection device contains a gas pressure chamber which has an aperture along the target path for unobstructed passage of the target flow and which is filled with a buffer gas that is maintained at a pressure of some 10 mbar.
