- 論文の詳細を見る
TOKASTAR, a hybrid magnetic configuration between tokamak and stellarator, has been proposed for the study of magnetic confinement optimization. The construction of the small device named TOKASTAR-2 was started in April 2008, and completed in March 2009. As a preliminary experiment, spatial distribution of electron temperature (Te) and electron density (ne) are measured in a simple toroidal magnetic field configuration. Initial ECH plasmas with Te ∼ 10 eV, ne ∼ 1016 m－3 are confirmed. In the preliminary experiment of ohmic heating plasma production, plasma current (Ip) of 25 A is observed. The plasma equilibrium is calculated by the TOSCA code, and the magnetic flux surface and optimal vertical field coil currents are clarified for the future experiment.
