Gas Feeding System Supplying the U-400M Cyclotron Ion Source with Hydrogen Isotopes

Automated system feeding into ion source hydrogen isotopes as molecules with preset ratio of the fluxes is described. The control system automatically maintained the working parameters and provided graphic and digital representation of the controlled processes. The radiofrequency (RF) ion source installed at the axial injection line of the cyclotron produced ion beams of HD⁺, HT⁺, DT⁺, D₂H⁺, etc. At a several months DT⁺ beam acceleration the tritium consumption was less than 108 Bq/hr. The intensity of a 58.2 MeV triton beam (T⁺ ions) extracted from the cyclotron chamber was about 10 nA.
