CSTN-IV

CSTN-IV is a tokamak-type plasma device with the plasma electric current of 1kA and electronic temperaturefrom 10-20eV. The maximum discharge pulse is 20ms, but, with this device rare high repetition quality, complete interchange discharge and high repetition pulse discharge of operational duty 50% is possible. Also the simulation of long time discharge has become possible. It is regarding the basic research of tokamak-type fundamental physics of surface plasma control.
