CEA-DSM-DAPNIA-SACM contribution to IFMIF 2004

A neutron source from the D-Li stripping reaction has been selected as the basic concept of the international fusion materials irradiation facility (IFMIF). The objective requires generation by a linear accelerator of 250 mA continuous current of deuterons at a nominal energy of 40 MeV, with provision for operation at lower energy. The basic approach is to provide 2 linacs modules, each delivering 125 mA to a common lithium target. This approach presents availability and operational flexibility advantages. This paper reviews the technical choices that have been made for different components such as the ECR source, beam diagnostics, the radio frequency quadrupole, the RF system, the drift-tube-linac and the high energy beam transport line.
