Description

In order to study the neutronics of fusion reactor blankets, a program is underway at the IPR using 14-MeV neutron source. An accelerator based neutron generator is under development in which 30 mA deuterium beam will be accelerated up to 300 keV energy. It will then impinge on a rotating tritium target to producing nearly isotropic 14-MeV neutrons. The expected neutron yield is 3-5 x 10¹²12 n/s. The rotating target has been developed for intense neutron source. Total estimated power density on the rotating target is 11.5 kW/cm²2 for the diameter and power of D⁺ + beam are 10mm and 9kW (300kV,30mA). The simulation by CFD method have been carried out to investigate the heat transfer in rotating target system. In this paper, the design and analysis of the rotating tritium target system of intense neutron source is discussed and result of beam test performed using D⁺ + beam at 90keV, 20mA, 15mm beam diameter, resulting 1 kW/cm² 2 beam power stopped at the surface of dummy copper disk 3mm in thickness and 180 mm in diameter is presented.
