| Summary: | Заглавие с экрана The paper presents an experimental evidence of the formation of energetic charge-exchange neutral atoms in a self-magnetically insulated diode with a graphite potential electrode. The experiments have been carried out using both a diode with externally applied magnetic insulation (single-pulse mode: 100 ns, 250-300 kV) and a diode with self-magnetic insulation (double-pulse mode: the first negative pulse 300-500 ns, 100-150 kV followed by the second positive pulse 150 ns, 250-300 kV). The ion beam energy density was measured using an infrared imaging diagnostics of thin metal targets, which intercept the beam. It was also calculated using the waveforms of ion current density and accelerated voltage. For self-magnetically insulated diode in double pulse mode infrared measurements exceed the Faraday cup measurements indicating that neutrals are present in the beam. For applied Br diode in single pulse mode infrared measurements agree with the Faraday cup measurements indicating that neutrals are not present in the beam. The ability of production of large fluxes of energetic neutrals in an ion diode with self-magnetic insulation is shown. With the energy of neutrals of 3-5 keV, the fluence can reach up to (2-4)-10 15 cm -2 per pulse. Режим доступа: по договору с организацией-держателем ресурса |
