抄録

A very high beta value was obtained during pulsed poloidal current drive (PPCD) operation in a reversed-field pinch (RFP) plasma during a TPE-RX experiment. Poloidal beta is almost equal to total beta in the RFP, and is as high as 30% near the end of PPCD operation. During the PPCD operation, the magnetic fluctuation associated with the dynamo effect is reduced, and improved confinement is realized, which results in this high beta value.
