| Popis: | The generation of triatomic H3+ and D3+ ions in a reflex hollow-cathode discharge using hydrogen and deuterium as the working gas, over a wide range of operating pressure, discharge current and magnetic field strength was explored. The fractional ion species composition of the extracted ion beam was monitored using a time-of-flight method. The maximum fraction of H3+ that could be obtained was as high as 95%, with similar results for D3+ ions. It was shown that the degree of ionization of the working gas is one of parameters determining the ion composition of the hollow cathode discharge plasma. |
