Abstract:
1. An arrangement for generating intensive radiation based on a plasma, comprising: a target generator with a nozzle for metering and orientation of a target flow for plasma generation; a vacuum chamber; and a high-energy excitation radiation being directed to the target flow in the vacuum chamber and the target flow being completely converted piece by piece by a defined pulse energy of the excitation radiation into a plasma having a high conversion efficiency for the intensive radiation in a desired wavelength region; said nozzle of the target generator being a multiple-channel nozzle with a plurality of separate orifices, the orifices generating a plurality of target jets, the excitation radiation for generating plasma being directed simultaneously portion by portion to the target jets within a spot of radiation; said separate orifices of the nozzle being arranged in such a way that the target jets fill the radiation spot of the excitation radiation without gaps and without overlapping, wherein the orifices are arranged offset although the target jets appear closed to one another in the radiation spot.
