ARC-ECRIS is an Electron Cyclotron Resonance Ion Source (ECRIS) based on arc-shaped coils unlike the conventional[1] ECRIS which bases on a multipole magnet (usually a hexapole magnet) inside a solenoid magnet.[2]

Magnet structure of the first ARC-ECRIS prototype constructed at JYFL Accelerator Laboratory

First time the arc-shaped coils were used already in the 1960s in fusion experiments, for example at the Lawrence Livermore National Laboratory (MFTF, Baseball II,[3] ...) and later in Japan (GAMMA10, ...).

In 2006 the JYFL ion source group[4] 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).
