International Fusion Materials Irradiation Facility (IFMIF) accelerator system conceptual design activity
- Los Alamos National Lab., NM (United States)
The International Fusion Materials Irradiation Facility (IFMIF) requires generation, by a linear accelerator (linac), of 250 mA continuous current of deuterons at a nominal energy of 35 MeV, with provision for operation at 30 MeV and 40 MeV. The basic approach is to provide two linac modules, each delivering 125 mA to a common target for a total of 10 MW of continuous beam power. The deuterons would be stripped in a molten lithium target to two neutrons, with a neutron energy spectrum peaked at {approximately}14 MeV as would be found in a fusion device. The accelerator has dual deuteron ion sources, and a low-energy beam transport to a 175 MHz radio frequency quadrupole (RFQ) buncher and preaccelerator up to {approximately}8 MeV. For the main accelerating structure from 8--40 MeV, two different technologies are under consideration; normal-conducting accelerating structures made from copper, or superconducting niobium structures. Determining which is the better approach is a complex question involving physics, engineering, cost, and operational availability. Conceptual design activities are now in progress under a formal Conceptual Design Activity, organized via the IEA. These activities involving the US, Russia, Japan, and the European Community, are described.
