Radial structure of large-scale plasma perturbations in the T-10 tokamak

Irradiation out of tokamak plasma includes information on instabilities developing in a plasma. The paper deals with the measuring of variable components of intensities of soft X radiation and bremsstrahlung in the visible range, coherent with oscillations of poloidal magnetic field m=2 in the T-10 tokamak. To separate variable components the method of synchronous detection is used. A conclusion is made based on the basis of proposed interpretation of the results obtained, on the radius of rational magnetic surface q=2 and with of magnetic island. Data on the surface radius q=2 are compared with the results of calculation according to Spitzer formula proceeding from profiles of electron temperature and effective charge of a plasma
