摘要：

The ITER neutral beam injection system consists of three 17 MW, 1 MeV D-0 injectors attached to three adjacent tokamak ports, arranged to produce beams tangential to the toroidal field at a radius of 6.5 m. The paper describes the 'physics' design of the injectors which will heal drive current in, and induce plasma rotation of, the ITER plasma. Each injector uses a single, large, caesiated volume are discharge ion source and an electrostatic accelerator. The D- beam is neutralized in a gas neutralizer and the remaining charged fraction is separated from the neutral beam in an electrostatic residual ion dump (RID). The pressure at the exit of the accelerator and downstream the neutralizer is kept low by a cryopump surrounding the neutralizer and the RID. A calorimeter located downstream the RID allows the injectors to be commissioned independently of ITER.
