A duoplasmatron ion source capable of delivering 20 mA of deuteron beam at an energy of 20 keV has been designed. This ion source will inject the beam into an RFQ accelerator, which is intended to be used as a 14-MeV neutron generator. In this design the emphasis is laid on the design of the plasma expansion cup and the extraction geometry. The space-charge beam dynamics through the ion source and the einzel lens is investigated with the help of a computer code IORA developed by us. Almost all the components of the ion source have been made. The solenoid magnet and the intermediate electrode have been tested. The full assembly and the testing of the various parts is underway.
