Arc-ecris
Encyclopedia
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
Solenoid
A solenoid is a coil wound into a tightly packed helix. In physics, the term solenoid refers to a long, thin loop of wire, often wrapped around a metallic core, which produces a magnetic field when an electric current is passed through it. Solenoids are important because they can create...
. 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, ...) and later in Japan (GAMMA10, ...). 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
Plasma (physics)
In physics and chemistry, plasma is a state of matter similar to gas in which a certain portion of the particles are ionized. Heating a gas may ionize its molecules or atoms , thus turning it into a plasma, which contains charged particles: positive ions and negative electrons or ions...
can be confined in an arc-coil magnetic field structure (see references).
