    摘要: A method to align a discharge axis of a discharge radiation source with respect to optics of the lithographic apparatus includes creating a discharge in a substance in a discharge space between an anode and a cathode to form a plasma so as to generate electromagnetic radiation. The discharge is triggered by irradiating an area on a surface proximate the discharge space with an energetic beam. The position of the area is controlled in response to a property of the radiation in the lithographic apparatus and/or the temperature of a collector of the lithographic apparatus. Controlling the position of the area which is irradiated improves alignment of the discharge axis with the different lithographic modules, such as the contamination barrier, the illumination system, the substrate table and/or the projection system.

    摘要: A lithographic apparatus includes a radiation system for providing a beam of radiation from radiation emitted by a radiation source. The radiation system includes a contaminant trap for trapping material emanating from the radiation source. The rotation contaminant trap includes a multiple number of elements extending in a radial direction from a common rotation trap axis and being arranged for allowing contaminant material emanating from the radiation source to deposit during propagation of the radiation beam in the radiation system. The radiation system further includes a contaminant catch for receiving contaminant material particles from the rotation trap elements, the contaminant catch having a constitution, during operation of the radiation, for retaining said contaminant material particles.
