    Abstract: A gas laser for emitting ultraviolet laser light with a wave length of 248-249 nm, the gas mixture in the resonance chamber containing krypton, fluor or a fluor compound, and argon in such quantities that at room temperature the partial argon pressure exceeds 0.5 bar and the partial pressure of krypton and fluor or the fluor compound is smaller than 0.2 bar. The gas mixture in the resonance chamber also contains neon in such a quantity that its partial pressure at room temperature is at least equal to that of the argon.

    Abstract: 1,166,755. Thermonuclear apparatus. STICHTING VOOR FUNDAMENTEEL ONDERZOEK DER MATERIE. 4 July, 1967 [7 July, 1966], No. 30749/67. Heading G6P. In a thermonuclear fusion device, a toroidal plasma is enclosed within a cold gas blanket inside a containment vessel. The gas is injected through pipes tangential to the containment vessel so as to cause the gas to rotate about the toroidal axis. By centrifugal action the gas assumes a position surrounding the plasma. External coils produce the internal toroidal magnetic field. A current is induced in the plasma by further external coils to effect plasma heating.

    IPC: G21K1/06

    Abstract: Multi-layer mirror for radiation with a wavelength in the wavelength range between 0.1 nm and 30 nm, comprising a stack of thin films substantially comprising scattering particles which scatter the radiation, which thin films are separated by separating layers with a thickness in the order of magnitude of the wavelength of the radiation, which separating layers substantially comprise non-scattering particles which do not scatter the radiation, wherein the separating layers are covered on at least one side in each case by an intermediate layer of a material which can be mixed with the material of the thin films and the material of the separating layers.
