The SPIDER Code - Axisymmetric Fixed Boundary Plasma Equilibrium Solver
Abstract:
The SPIDER code is an axisymmetric fixed boundary plasma equilibrium solver for different formulations of the tokamak plasma equilibrium problem. Plasma with nested magnetic surfaces and a single magnetic axis limited by prescribed fixed boundary is assumed. Any reasonable set of two flux functions that can define toroidal current density profile (right hand side of the Grad-Shafranov equilibrium equation) can be prescribed as an input. High speed of the SPIDER code and high accuracy of computations make the code a powerful tool to solve complicated toroidal plasma equilibrium problems (such as plasma equilibrium with high beta, with high elongation of the plasma boundary, with low aspect ratio and with large Shafranov shift, with x-point at the plasma boundary, plasma profiles with reverse shear and with nonzero current density at plasma boundary etc.). Simple input and output formats make possible to use the SPIDER code in many tokamak plasma applications.
