| Abstract: | The linear behavior of the double tearing mode (DTM) mediated by parallel electron viscosity in cylindrical plasmas with reversed magnetic shear is numerically investigated. The mode structures and dispersion relations for linearly unstable modes are calculated. A detailed analysis of linear instability characteristics of DTMs with various roles, including the inter-resonance distance, the electron viscosity Reynolds number and poloidal mode number, is performed. |
