  • Foil trap and light source device using such foil trap
    Patent number: 9599812
    Abstract: Disclosed herein a rotational type foil trap that is capable of avoiding the transmission rate of the EUV light to be lowered even when the EUV light source operates with the high input power and also suppressing the temperature increase of the foil to attain a sufficient life duration. In the rotational type foil trap, one end of each of foils is inserted into each of a plurality of grooves provided on a side face of a center support, and the center support and the each of the foils are fixed together by brazing.
    Type: Grant

  • GAS-DISCHARGE LAMP
    Publication number: 20140015396
    Abstract: The invention describes a gas-discharge lamp (1) comprising a discharge vessel (11) arranged in an outer quartz glass envelope (12), which gas-discharge lamp (1) comprises a local thermal area contact (2) between a lower surface (21) of a localised deformation (20) of the outer envelope (12) and a corresponding isolated area (22) on the outer surface (23) of the discharge vessel (11). The invention also describes a method of manufacturing a gas-discharge lamp (1), which method comprises the steps of arranging a discharge vessel (11) in an outer quartz glass envelope (12); forming a localised deformation (20) of the outer envelope (12) to create a local thermal area contact (2) between a lower surface (21) of the localised deformation (20) and a corresponding isolated area (22) on the outer surface (23) of the discharge vessel (11).

  • MERCURY-FREE HIGH-INTENSITY GAS-DISCHARGE LAMP
    Publication number: 20120098423
    Abstract: The invention describes a mercury-free high-intensity gas-discharge lamp (1) comprising a discharge vessel (5) enclosing a filling in a discharge chamber (2) and comprising a pair of electrodes (3, 3?, 4, 4?) extending into the discharge chamber (2), for which lamp (1) the electrodes (3, 3?, 4, 4?) are free of thorium, and the filling includes a halide composition comprising at least 6 wt % thorium iodide.
