Abstract:
1. An arrangement for generating extreme ultraviolet radiation based on an electrically operated gas discharge comprising: a discharge chamber, having 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 being mounted so as to be rotatable about an axis of rotation; an energy beam source for directing an energy beam to the discharge area; a high-voltage power supply connected to the electrodes for generating high-voltage pulses; said high-voltage power supply having a capacitor battery comprising a plurality of parallel connected capacitor elements which are arranged along at least one ring concentric to said axis of rotation and arranged in a ring plane being parallel to the disk-shaped electrodes; and electrical connections being guided from the capacitor elements to each of the disk-shaped electrodes along separate rings being concentric to the axis of rotation.
