So the influence of foreign objects on power carrying capacity reduction of the operating system has attracted scholars’ extensive attention. In most cases, the sizes of foreign objects are much less than the operating wavelength, so, it is close to practical case that we suppose that the foreign object is in a uniform external field.展开更多

It can be inferred from the simulation results that at the core of the device, the tokamak should possess a three-dimensional magnetic field configuration, which could be reduced to a two-dimensional one when the radial position is greater than 0.6a. The radial magnetic field and the amzimuthal magnetic field have the same order of magnitude at the core of the device. These results can offer a reference for the analysis of the plasma instability, the property of the core plasma, and the magnetic field measurement.展开更多
