Abstract:
A high power extreme ultraviolet (EUV) beam is produced. An electron beam is injected in a compact electron storage ring configured for emission of free-electron laser (FEL) radiation. The electron beam is passed through a magnetic undulator on each of a plurality of successive revolutions of the electron beam around the compact electron storage ring. The electron beam is induced to microbunch and radiate coherently while passing through the magnetic undulator. A portion of the free-electron laser radiation at an extreme ultraviolet wavelength produced by an interaction of the electron beam through the magnetic undulator is outputted.

Claim (Index 1):
A system for producing a high power extreme ultraviolet (EUV) beam, including:\n a compact electron storage ring configured for emission of free-electron laser (FEL) radiation; an electron injector configured to insert an electron beam into the compact electron storage ring; a plurality of bending magnets and a plurality of quadrupole magnets interspersed along the compact electron storage ring, wherein at least a corresponding one of the quadrupole magnets is between any two of the bending magnets along the compact electron storage ring; a magnetic undulator configured to allow the electron beam to pass through the magnetic undulator where the electron beam is induced to microbunch and radiate coherently; and an exit aperture configured to output a portion of the free-electron laser radiation at an extreme ultraviolet wavelength produced by an interaction of the electron beam through the magnetic undulator, wherein the output portion of the free-electron laser radiation is provided to a lithography system as a light source for the lithography system and an average power of the output portion of the free-electron laser radiation is greater than 250 W.
