Upgrading of the Magnetic Confinement Plasma Device KT-5E

【摘要】 In this article we present ideas of providing appropriate poloidal magnetic field for helimaks to help to generate toroidal magnetic plasma torus.Placing a conductive ring in the center of the cross-section to induce a suitable current,we change the helical magnetic field lines in the helimak discharge into magnetic surface.In this kind of discharge,the plasma density is greatly increased,and the corresponding density fluctuation is significantly decreased,showing a better confinement by magnetic shear.It allows more flexible and efficient experimental investigations on the toroidal magnetic confinement plasmas to be carried on in this kind of device.更多还原
