Research Abstract

Magnetic reconnection is one of dynamic plasma phenomena appear in such as solar flare, terestrial magnetosphere and tokamak plasmas. We have investigated and clarified the fast process of topology change by magnetic analysis, fast CCD camera and soft X-ray CT, when a microwave energy pulse is injected into the helical field lines in the LATE device, a plasma is produced by electron cyclotron resonance and a toroidal current is generated spontaneously and increases resulting in formation of closed flux surfaces.
