  • X-ray tube anode arrangement
    Patent number: 9911569
    Abstract: A method of manufacturing an X-ray tube component, includes diffusion bonding or brazing an anode of rhodium, molybdenum or tungsten to a heat spreader of molybdenum, tungsten, or a composite of molybdenum and/or tungsten. Suitable joint materials for diffusion bonding include gold; suitable joint materials for brazing include an alloy of silver and copper, an alloy of silver, copper and palladium, an alloy of gold and copper or an alloy of gold, copper and nickel. The resulting tube component delivers reliable behaviors and the joint can withstand high temperatures, high temperature gradients, fast temperature changes, extremely high radiation and extremely high electric field, while maintaining good high vacuum properties.
    Type: Grant
    Filed: January 12, 2016
    Date of Patent: March 6, 2018
    Assignee: Malvern Panalytical B.V.
    Inventors: J. van der Borst, Bart Filmer, Ben Hageluken, Jos Schalley, Romulus Mihalca

  • X-ray source with metal wire cathode
    Patent number: 8223923
    Abstract: An X-ray source with a cathode (2) that includes a first wire (4) having optionally thermal loops (12, 14) between an emission loop (10) and first and second ends (6, 8). A spiral second wire (30) is wound around the wire (4) and a low work function coating (32) is provided on both wires. The first and second wires may be of refractory material, such as tungsten, and the low work function coating may include barium oxide.
