    Abstract: A process for repairing a damaged annular region of an anode configured to emit x-rays includes the step of machining the damaged annular region made of an initial target coating to a depth smaller than a thickness of the coating so as to leave behind a residual annular layer. An intermediate layer is then deposited on the residual annular layer. A repairing layer is then deposited on the intermediate layer. A heat treatment is then performed using an anneal which causes, by interdiffusion and formation of a solid solution, the material of the intermediate layer and the material of the residual annular layer to diffuse into each other and further cause the material of the intermediate layer and the material of the repairing layer diffuse into each other. As a result of this anneal the intermediate layer disappears.

  • Patent number: 10005129
    Abstract: This invention relates to a method of forming sections of seamless titanium or titanium alloy pipe. The method involves providing a substrate for forming pipe and a sleeve of a section of pipe on the substrate. The pipe section has an end from which the substrate projects. The pipe is formed by spraying particles of titanium or titanium alloy generally parallel to a longitudinal axis of the substrate to impact a face of the end and to cause particles to bond to and to accumulate on the pipe end to form pipe. The method further involves moving formed pipe longitudinally relative to the substrate to remove formed pipe from the pipe-forming substrate and continuing to spray titanium or titanium alloy particles onto the end face to cause further pipe to form continuously and integrally with the formed pipe. This enables a seamless titanium or titanium alloy pipe to be formed of any desired length.

    Abstract: A radiation source for generating EUV radiation includes a laser configured to fire laser pulses at a target area to which is supplied a stream of fuel droplets, which may be tin droplets that emit EUV radiation when excited by the laser beam. The EUV radiation is collected by a collector. The tin droplets may be pre-conditioned by a laser pre-pulse before the main laser pulse to change the shape of the droplets so that the droplets are in an optimum condition for receiving the main laser pulse. Embodiments of the invention take into account the effect of the vaporization of one fuel droplet on succeeding droplets and allow the timing of the main and/or pre-pulse to be adjusted to take into account any delay in arrival of the subsequent droplet or oscillations in the shape of the subsequent droplet which may be caused by vaporization of the preceding droplet.
