Comparison of the calculations of the stability properties of a specific stellarator equilibrium with different MHD stability codes

A particular configuration of the LHD stellarator with an unusually flat pressure profile has been chosen to be a test case for comparison of the MHD stability property predictions of different three-dimensional and averaged codes for the purpose of code comparison and validation. In particular, two relatively localized instabilities, the fastest growing modes with toroidal mode numbers n = 2 and n = 3, were studied using several different codes, with the good agreement that has been found providing justification for the use of any of them for equilibria of the type considered.
