  • X-Ray device and deposition process for manufacture
    Patent number: 6477235
    Abstract: A method of manufacturing an X-ray device is described including the step of coupling a housing that includes diamond to an anode structure that includes diamond. Further, a target metal may be formed on a tip of the anode structure. An X-ray device is also described including a housing made of diamond, a cathode within the housing, and an anode structure that includes diamond. The anode structure may include conductive diamond, while the housing structure may include high resistivity diamond.
    Type: Grant

  • Cathode structure with getter material and diamond film, and methods of manufacture thereof
    Patent number: 6465954
    Abstract: A cathode structure comprising a getter material provided with a diamond film. The getter material may include zirconium, vanadium and iron. Cathode structures may have a substantially rounded configuration including a substantially straight portion. Other cathode structures may have a substantially flat portion, with the diamond film covering essentially the entire flat surface. Methods of manufacturing cathode structures may include conditioning the cathode structure by applying a voltage.

  • Method and x-ray device using pulse high voltage source
    Patent number: 6069938
    Abstract: An apparatus and method for exposing a treatment site in a patient to x-ray radiation is described that uses a pulse voltage source, where the x-ray emitter employs a cold cathode. The invention may further include a current sensor for measuring a current through the x-ray emitter, and, optionally, a current integrator connected to the current sensor. Each voltage pulse may be discontinued when a predetermined amount of charge has passed through the emitter. The step of moving an x-ray emitter past a treatment area at a rate determined by the amount of charge that has passed through the emitter is also described. The present invention also includes an x-ray emitter device with rectangular voltage pulses added to a base direct current voltage. Another step of the invention may be applying a voltage pulse cycle to the x-ray emitter where a duration of the pulse is 2-5 times lower than a thermal relaxation time of an emitter.
