Manufacturing of the full size prototype of the ion source for the ITER neutral beam injector - The SPIDER beam source

摘要

In ITER, each heating neutral beam injector (HNB) will deliver about 16.5 MW heating power by accelerating a 40 A deuterium negative ion beam up to the energy of 1 MeV. The ions are generated inside a caesiated negative ion source, where the injected H-2/D-2 is ionized by a radio frequency electromagnetic field.
