Effect of Specific Pressure of Fast Particles on Double-Tearing Mode of Resistance Magnetic Fluid

In the advanced Tokamak magnetic field configuration, the instability of the double tear mode excited by the diamagnetic shear configuration plays an important role. At the same time, due to the fusion reaction and auxiliary heating means, a large number of fast particles will be generated. The existence of fast particles will affect the growth of double tear mode. In the context of resistive magnetic fluids, the role of fast particle specific pressure in the instability of the double tear mode was analyzed, and the CLT-K program was used to simulate the instability of the fast particle specific pressure to the double-tearing mode to explore the physical mechanism of its impact.
