Patent ID: 7557366

Claim:
An apparatus for producing radiation by an electrically operated discharge, comprising: a first electrode and a second electrode, the first and second electrode being configured at a distance from each other which allows ignition of a plasma in a gaseous medium between the first and second electrode; a capacitor bank electrically connected at a first terminal to the first electrode and at a second terminal to the second electrode, the capacitor bank configured to store a discharge energy needed for the ignition of the plasma, the first electrode, second electrode and capacitor bank forming an electric circuit, wherein at least the first electrode is formed by an electrically conducting fluid supplied via a first feeding line, the apparatus further comprising a charger connected to the first terminal and/or the second terminal configured to charge the capacitor bank in a time varying manner; and a first high inductance unit provided upstream of the first terminal in the first feeding line for electrically decoupling the electric circuit.
