摘要： Disclosed is an illumination source comprising a gas delivery system comprising a gas nozzle. The gas nozzle comprises an opening in an exit plane of the gas nozzle. The gas delivery system is configured to provide a gas flow from the opening for generating an emitted radiation at an interaction region. The illumination source is configured to receive a pump radiation having a propagation direction and to provide the pump radiation in the gas flow. A geometry shape of the gas nozzle is adapted to shape a profile of the gas flow such that gas density of the gas flow first increases to a maximum value and subsequently falls sharply in a cut-off region along the propagation direction.

摘要： An assembly comprises a space configured for placing a medium to receive a first radiation for generating a second radiation. In operation, the second radiation propagates coaxially with the first radiation after the medium. The assembly further comprises an optical element after the medium for transmitting or reflecting the first radiation with a surface area. The assembly is configured such that, in operation, a cleaning gas is in contact with the surface area. A reactive medium is generated from at least a part of the cleaning gas by the second radiation for removing a contamination from the surface area.

摘要： A method for controlling a density distribution of electrons provided by an electron source for use in hard X-ray, soft X-ray and/or extreme ultraviolet generation, the method comprising generating a plurality of electrons from a pattern of ultracold excited atoms using an ionization laser inside a cavity, wherein the electrons have a density distribution determined by at least one of the patterns of excited atoms and the ionization laser, and accelerating the electrons out of the cavity using a non-static acceleration profile, wherein the acceleration profile controls the density distribution of the electrons as they exit the cavity.
