Abstract
A method for studying the central plasma structure using soft X-ray signals in the HT-7 tokamak is reported. Through analysing a typical discharge with MHD instability, the position and rotation direction of magnetic island are obtained from the soft X-ray signals. The magnetic island position and rotation direction are validated from the contour map of soft X-ray emissivity and the m=2 mode rotation direction observed on the Mirnov signals.
