Numerical calculations have been performed to study the MilD activity in high-,3 tokamaks such as ISX-B. These initial value calculations build on earlier low ~techniques, but the i3 effects create several new numerical issues. These issues are discussed and resolved. In addition to time-stepping mo

β¦ Synopsis
The CASTOR (complex AlfvΓ©n spectrum of toroidal plasmas) code computes the entire spectrum of normal-modes in resistive MHD for general tokamak configurations. The applied Galerkin method, in conjunction with a Fourier finite-element discretisation, leads to a large scale eigenvalue problem Ax = Ξ»Bx, where A is a nonself-adjoint matrix.

A matrix method to solve a resistive MHD stability problem has been developed. The equations are reduced to an eigenvalue problem of block tridiagonal matrices. The inverse iteration method is employed as a solution method of the eigenvalue problem.
The reduced magneto-hydro-dynamical (MHD) equations show that the pressure gradient together with the magnetic-field curvature as a force drives the plasma short-wavelength MHD instability in a toroidal system. This paper discusses the role of magnetic curvature of tokamak plasmas in some detail. It
