Self-extraction negative ion source [PDF]
Review of Scientific Instruments, 1982 A large multicusp negative ion source has been constructed to generate H− or D− ions for high-energy neutral beam systems. With the presence of cesium, the source has produced a steady-state H− ion beam current greater than 1 A with an impurity level less than 1%. The vertical and horizontal profiles of the self-extracted beam have been measured with a

A negative ion source for alkali ions [PDF]
Nuclear Instruments and Methods, 1980 An ion source is described which delivers negative alkali ions. With this source, which consists of a duoplasmatron and a charge exchange canal with alkali vapour, negative Li, Na and K ions are produced. The oven in which alkali metals are evaporated can reach temperatures up to 575°C.
