Beam sources.

The second field of use of negative ion sources appeared in the early 1970s in relation with the projects of magnetic fusion. Berkner et al. 8 reported that the acceleration of negative deuterium ions (D −) was the only possible way to achieve efficient neutral beam injection (NBI) into fusion devices with the beam energy exceeding 100 keV per nucleon (see also Ref. 9).
