Effect of magnetic shearing on thermal transport of electrons in magnetic islands
The influence of magnetic shear parameters on the electron temperature distribution and heat transport in the magnetic island were studied by numerically solving the tokamak plasma energy transport equation.The results show that for different radial distributions of the safety factor,the magnitude of the magnetic shear parameter will affect the magnitude of the effective radial heat transport coefficient.The higher the shear degree,the greater the effective radial heat transport χrcoefficient.And when the magnetic field perturbation degree is high enough,the effect of high shear on radial heat transport χrwill be reduced.
