Calculation of Internal Inductance and Poloidal Beta Using Solovev's Assumption in a Circular Cross Section Tokamak

摘要

We calculated the internal inductance and the poloidal beta in a circular cross section Tokamak using Solov'ev assumption in the solution of Grad-Shafranov equation (GSE). GSE is solved by considering linear source functions and fixed boundary conditions. This solution has the three quantities (plasma current I_p, plasma minor radius r_p and β_p + l_i/2) that they are as input data. In two different discharges on IR-T1 Tokamak with this solution, we have shown that the internal inductance at a low value is required to extend the duration of Tokamak plasma discharge that it is consistence with other method.
