Abstract :
A novel Abel inversion method has been employed to obtain the precise electron density profile from chordal interferometric measurements on J-TEXT tokamak, in which the Gauss-Legendre integration method and dynamic boundary are introduced. To demonstrate the feasibility of this novel method, a hypothetical function I(x) is established, which resulted in a valid local value. Numerical results under different conditions are presented in the paper.
