  • ION GENERATING DEVICE AND NEUTRON GENERATING APPARATUS
    Publication number: 20100232559
    Abstract: A neutron generating apparatus includes an ion generating device. The ion generating device includes an ion generating tube to which deuterium gas or tritium gas is supplied, a magnet arranged outside of the ion generating tube for generating a magnetic field in the ion generating tube, a plasma generating antenna arranged outside of the ion generating tube for generating an electric field in the ion generating tube, and an RF power source that supplies high frequency power to the plasma generating antenna. The RF power source supplies the high frequency power to the plasma generating antenna by controlling the pulse thereof so that an unsteady state of plasma is generated repetitively in the ion generating tube.
