The Rotating Target Neutron Source (RTNS-II) facility provides an intense source of 14 MeV neutrons for the fusion energy programs of Japan and the United States. Each of the two identical accelerator-based neutron sources is capable of providing source strengths in excess of 3 × 1013n/s using deuteron beam currents up to 150 mA. At the present time, the facility operates a minimum total of twenty shifts (8 h) per week using both neutron sources. Because of funding cut-backs, future operations will be limited to one neutron source. The possibility exists to increase neutron output by combining the high voltage power supplies, thereby increasing the current capability of the operating neutron source. This would allow approximately a factor of three increase in neutron output. Using existing equipment, an ion source test stand has been constructed to improve ion source output. Conceptual design studies have been made concerning a factor of ten increase in neutron output. Detailed studies of needed target improvements have been made and will be discussed. The present status of the facility, as well as the various upgrade options, will be described in detail. |
