Soft X-ray tomography on HT-6B tokamak

Description
The tomography method for deriving soft X-ray local emissivities on HT-6B tokamak, using one horizontal array of 23 soft X-ray detectors, is described. This method has been applied to study of sawtooth oscillation and large m = 1 oscillation on HT-6B tokamak. It has been found that the large m = 1 oscillation on soft X-ray signal is caused by the rotation of plasma column containing perturbation. The reconstructed images in the phase before a sawtooth crash have shown the hot plasma core move gradually toward one side, this is considered that as the increasing m=1 kink mode.
