The drift source: A negative ion source module for direct current multiampere ion beams
The concept of a modular large size ion source is under investigation in our laboratory for the development of the very intense (tens of amperes) negative ion (D-) beams needed for neutral beam injection in thermonuclear fusion research. The basic idea is to develop a compact small ion source producing the required ion flux (20-30 mA/cm2) over a total surface of about 200 cm2 and designed in such a way that it can easily be juxtaposed with other identical modules. A large negative ion source of any size (e.g. approximately equals 1.0 m2 for an ignition device to test engineering concepts) of the present ion sources. In this context, we have developed and tested a source module, called the DRIFT source, whose main properties are presented in this article.
