MAGNETIC SYSTEM FORMING ISO SURFACES CLOSED MODULES FROM 'CUSP' TYPE MAGNETIC STRUCTURES AND RCE-TYPE ION SOURCES USING SUCH A SYSTEM

摘要

The invention relates to a device for generating a magnetic field such that it is possible to create closed iso-module surfaces and this in the context of a planar symmetry and magnetic structures of "cusp" type; The subject of the invention is also a source of ions of the RCE (Electronic Cyclotron Resonance) type using such a device (M1 and M2) comprising means for injecting a high frequency wave (B1), means for gas injection (B2, B3), a high voltage polarized plasma electrode (B6), a polarized extraction electrode (B7) to thereby form an ion beam (B5) rooms.
