    摘要: A cleaning arrangement for an optical system and in particular for an optical system designed for EUV radiation. The cleaning arrangement has a gas inlet (28) for a reactive gas (29). Contaminants (23) that have deposited on the surface of optical elements (110) are detached by the reactive gas. Also provided are getter surfaces (32) that are preferably arranged opposite the surfaces to be clean and by which the contaminants detached from these surfaces are absorbed. This absorption may take place as a result of condensation on the getter surface and also by chemical reaction.

    摘要: The present invention relates to a method of cleaning and after treatment of optical surfaces in an irradiation unit, said irradiation unit comprising a radiation source (1, 31) emitting EUV-radiation and/or soft X-rays, a first volume (40) following said radiation source (1, 31) and containing first optical components (3, 33) with said optical surfaces, and a second volume (41) following said first volume (40) and containing second optical components (38). The method comprises at least one cleaning step in which a first gas or gas mixture is brought into contact with said optical surfaces, thereby forming volatile compounds with contaminations deposited on said optical surfaces, wherein said compounds are pumped out of the first volume (40) together with the first gas or gas mixture. In an after treatment step following said cleaning step the radiation source (1, 3) is operated once or several times in order to release residues of the cleaning step from the optical surfaces by irradiating said optical surfaces with said EUV-radiation or soft X-rays while the first volume (40) is separated from the second volume (41), wherein said released residues are pumped out of the first volume (40). With this method an improved cleaning result is achieved.

    摘要: The present invention relates to a method and device for generating optical radiation, in particular EUV radiation or soft x-rays, by means of an electrically operated discharge. A plasma (15) is ignited in a gaseous medium between at least two electrodes (1, 2), wherein said gaseous medium is produced at least partly from a liquid material (6) which is applied to a surface moving in the discharge space and is at least partially evaporated by one or several pulsed energy beams. In the proposed method and device the pulses (9) of said pulsed energy beams are directed to at least two different lateral locations with respect to a moving direction of said surface. With this measure, the radiation emission volume is expanded, less sensitive to spatial fluctuations and can be adapted better to the requirements of optical systems of any applications. Furthermore, the optical output power can be increased by this measure.
