  • Publication number: 20140362964
    Abstract: Isotope production system including a particle accelerator configured to produce a particle beam. The isotope production system also includes a target apparatus having a window configured to receive a particle beam and also separate production and condensing chambers. The production chamber is configured to contain a starting liquid and located so that the particle beam is incident upon the starting liquid thereby generating radioisotopes and transforming a portion of the starting liquid into vapor. The target apparatus also includes a fluid channel that extends between and fluidly couples the production and condensing chambers. The fluid channel is configured to allow the vapor to flow from the production chamber into the condensing chamber. The condensing chamber is configured to transform the vapor in the condensing chamber into a condensed liquid.

  • Patent number: 8653762
    Abstract: A particle accelerator including an electrical field system and a magnetic field system that are configured to direct charged particles along a desired path within an acceleration chamber. The particle accelerator also includes a mechanical device that is located within the acceleration chamber. The mechanical device is configured to be selectively moved to different positions within the acceleration chamber. The particle accelerator also includes an electromechanical (EM) motor having a connector component and piezoelectric elements that are operatively coupled to the connector component. The connector component is operatively attached to the mechanical device. The EM motor drives the connector component when the piezoelectric elements are activated thereby moving the mechanical device.

  • Patent number: 8153997
    Abstract: A cyclotron that includes a magnet yoke having a yoke body that surrounds an acceleration chamber. The cyclotron also includes a magnet assembly to produce magnetic fields to direct charged particles along a desired path. The magnet assembly is located in the acceleration chamber. The magnetic fields propagate through the acceleration chamber and within the magnet yoke, wherein a portion of the magnetic fields escapes outside of the magnet yoke as stray fields. The cyclotron also includes a vacuum pump that is coupled to the yoke body. The vacuum pump is configured to introduce a vacuum into the acceleration chamber. The magnet yoke is dimensioned such that the vacuum pump does not experience magnetic fields in excess of 75 Gauss.

  • Patent number: 8154374
    Abstract: A transformer winding having a conductor wound in a plurality of turns is disclosed, wherein the transformer winding includes a reinforcing part arranged at a winding transition in a manner so that the reinforcing part covers more than 180 degrees of the conductor circumference, whereby the bending strength of the conductor at the location of the reinforcing part is increased. The resistibility of the transformer winding against bending stress is hence improved.

  • Patent number: 8035946
    Abstract: An overvoltage protector circuit for telecommunication equipments is disclosed. The protector circuit includes a gas discharge tube connected to a communication line for passing any harmful surge currents appearing in the line to ground. A degradation detector circuit is arranged to detect any degradation of the gas discharge tube, the detector circuit comprises a reference gas discharge tube with a higher breakdown voltage than the supervised gas discharge tube and an alarm circuit loop connected to an alarm system. The alarm system is arranged to detect when current is breaking through the reference gas discharge tube and to initiate a degradation alarm.
