Abstract
The time evolution of magnetohydrodynamic activity, charge exchange neutral particles spectra, the line emission of the impurities in the visible spec tral range and soft x-ray radiation were investigated in the predisruption phase of the small Damavand tokamak [Amrollahi , Plasma Phys. Rep. 23, 561 (1997)]. The experimental data show that the main disruptive processes, par ticularly the kinetic, take place near the plasma periphery. The experiment al results also show that the interaction between high energy ions of bulk plasma and impurity ions may play an important role in the plasma radiation processes. A new mechanism for the plasma radiation processes in the predi sruption phase may be obtained that can be considered for the investigation of the disruption instability.
