REVERSED-FIELD PINCH EXPERIMENTS IN THE IFTES DEVICE

Reversed field pinch experiments have been performed by using a small size device, which is characterized a high aspect ratio and high curre nt density. The RFP configuration has been achieved as follows; the du ration is about 0.3 ms, the plasma current is 25 kA that corresponds t o the average current density exceeds 4 MA/m(2), and the loop voltage is about 40 V. In the plasma, we have observed asymmetry in the radial profile of the magnetic field and dynamic behavior of the RFP plasma disruption. From the relation between the toroidal magnetic flux and t he plasma current, the effective inductance is obtained and compared w ith the theoretical value.
