ARC-ECRIS (original) (raw)

ARC-ECRIS is an Electron Cyclotron Resonance Ion Source based on arc-shaped coils unlike the conventional ECRIS which bases on a multipole magnet (usually a hexapole magnet) inside a solenoid magnet. First time the arc-shaped coils were used already in the 1960s in fusion experiments, for example at the Lawrence Livermore National Laboratory (MFTF, , ...) and later in Japan . In 2006 the JYFL ion source group designed, constructed and tested similar plasma trap to produce highly charged heavy ion beams. The first tests were promising and showed that a stable plasma can be confined in an arc-coil magnetic field structure (see references).
