  • Neutron generator with a rotating target in a vacuum chamber
    Patent number: 10820404
    Abstract: A portable neutron generator is provided that does not utilize liquid cooling. The portable neutron generator includes a vacuum chamber housing defining a vacuum chamber and an ion beam inlet. The portable neutron generator also includes a rotating target positioned within the vacuum chamber. The ion beam inlet is oriented to receive ions such that the ions impinge upon the rotating target to cause neutrons to be emitted. The rotating target comprises a copper alloy. The portable neutron generator also includes a motor core positioned within the vacuum chamber and coupled to the rotating target. A motor stator is electromagnetically coupled with the motor core. The motor core is configured to rotate the rotating target at greater than 200 Hz during operation.

  • Electromagnetically enhanced contact separation in a circuit breaker
    Patent number: 9412549
    Abstract: Various embodiments of a circuit breaker are described where a movable bridge connector is employed as part of the conductive path when the circuit breaker is in a closed configuration. When the circuit is opened, the connector is displaced from the two fixed contacts otherwise bridged by the connector. In one such embodiment, the circuit breaker utilizes the electromagnetic forces generated in response to the opening event to break the circuit.
