Abstract
The rotating target neutron source at the Lawrence Livermore Laboratory (RTNS-I) is the most intense dc 14 MeV neutron source now in operation. The source consists of a 400 keV air-insulated accelerator which bombards a titanium tritide target rotating at 1100 rpm. A maximum source strength of 6 × 10 12 n/s can be produced by bombarding the target with a 20 mA beam of deuterons. Useful target life is ∼ 100 h. By extrapolation of the technology of the present source two new neutron sources (RTNS-II) have been designed to produce 4 × 10 13 n/s. These sources and the research facility to house them are now under construction. The facility will be operated by LLL as a national center for fusion reactor materials research.
