    Abstract: An extreme ultraviolet light source apparatus includes a disc-shaped cathode rotating about an axis, a disc-shaped anode rotating about an axis, an energy beam irradiation device irradiating a plasma raw material on the cathode with an energy beam to vaporize the plasma raw material, a power supply for causing a discharge between the cathode and the anode for generating a plasma in the gap between the cathode and the anode to emit extreme ultraviolet light, and an irradiation position adjusting mechanism for adjusting a position at which the cathode is irradiated with the energy beam. The cathode, the anode, and the irradiation position adjusting mechanism are accommodated in a housing. A photography device is disposed outside the housing and is configured to photograph a visible-light image of a vicinity of the cathode and the anode, the vicinity including visible light emitted from the plasma.

    Abstract: A mercury discharge lamp includes: a discharge tube having encapsulated therein mercury in the form of an amalgam; and a temperature control member that controls an ambient temperature of the amalgam in such a manner as to compensate for a change in the ambient temperature of the amalgam. The temperature control member may include a bimetal supporting the amalgam at a predetermined position, and the support member is formed or constituted by a bimetal. By the bimetal deforming in response to a change in the ambient temperature of the amalgam, the temperature control member changes a spaced-apart distance of the amalgam to a filament within the discharge tube and thereby changes an influence of heat generation by the filament on the amalgam. The temperature control member may include, near the amalgam, a resistance element whose resistance value changes in response to a temperature to control heat generation thereby.

    Abstract: The present invention relates to a device for the regulated temperature control of a gas discharge lamp, and a gas discharge lamp. The device according to the invention includes a transformer core of a transformer, the transformer core being designed for accommodating at least one discharge current-conducting connecting line of the gas discharge lamp as a primary winding. The transformer forms an energy source for heating a functional area of the gas discharge lamp that determines a function of the gas discharge lamp, and that is formed by an amalgam reservoir. The device also includes a secondary winding on the transformer core, and a means for temperature control that is used to regulate the energy that heats the amalgam reservoir. The means for temperature control is electrically connected to the secondary winding.

    Abstract: Disclosed are devices and methods related to flat gas discharge tubes (GDTs). In some embodiments, a plurality of GDTs can be fabricated from an insulator plate having a first side and a second side, with the insulator plate defining a plurality of openings. Each opening can be covered by first and second electrodes on the first and second sides of the insulator plate to thereby define an enclosed gas volume configured for GDT operation. Various examples related to such GDTs, including electrode configurations, opening configurations, pre-ionization features, grouping of a GDT with another GDT or device, and packaging configurations, are disclosed.
