Theory and Computer simulation Group
We research plasma physics in the open system especially the GAMMA10 tandem mirror, and are designing new magnetic configuration in order to improve GAMMA10.
We introduce some results in the following which were obtained until now.
１．Neoclassical transport
The neoclassical transport was calculated in the GAMMA10 magnetic field and so it was made clear that the non-ambipolar transport observed in the GAMMA10 experiments was the neoclassical transport.
２．Thermal barrier potential formation
New theory on the thermal barrier potential formation in a tandem mirror and its potential depth was built.
３．Mechanism of plug potential formation
New physical mechanism of plug potential formation was found in a tandem mirror, which agreed well with the experiments.
