Patent ID: 6881971

Claim:
An arrangement for the suppression of particle emission with generation of radiation based on a hot plasma, particularly with EUV radiation generation, comprising: a vacuum chamber for the purpose of generating the hot plasma, such chamber having an outlet opening for emitting the generated radiation from the vacuum chamber in a defined solid angle; means for generating an electric field, wherein at least one pair of electrodes with surfaces parallel to one another are provided for generating the electric field, wherein the electrodes communicate with different poles of a DC voltage source, are arranged parallel to a center axis of the beam bundle, and are positioned in such a way that the beam bundle is enclosed as closely as possible by the electrodes without the beam bundle being cut into, and wherein the electric field is oriented orthogonal to the central propagation direction of a divergent beam bundle exiting in a defined solid angle; and means for generating a gas sink so that a resulting particle flow is oriented parallel to the direction of the electric field, which means are arranged following the outlet opening of the vacuum chamber.
