Abstract:
1. An arrangement for generating extreme ultraviolet radiation by an electrically operated gas discharge, comprising: a discharge chamber which has a discharge area for a gas discharge for forming a plasma that emits the radiation; a first disk-shaped electrode and a second disk-shaped electrode, at least one of which electrodes being mounted so as to be rotatable and having an edge area to be coated with a molten metal; a liquid dispensing nozzle configured to apply the molten metal onto the edge area to be coated; an energy beam source for providing a pre-ionization beam; a discharge circuit connected to the electrodes for generating high-voltage pulses; and said edge area to be coated having at least one receiving area which extends circumferentially in a closed manner along the edge of a surface of the electrode and which is constructed so as to be adhesive for the molten metal and to which said liquid dispensing nozzle is directed for regenerative application of the molten metal.
