Second stability studies in a helical axis device: TJ-II
Abstract
The helical hard core in the four period TJ-II heliac permits access to a variety of magnetic configurations with very different magnetohydrodynamic properties. Here, a particular set of shearless configurations is presented with similar rotational transform at the magnetic axis, approximately equals 1.20, and slightly different values of the magnetic well that exhibit self-stabilization behavior to Mercier modes characteristic of a second stability regime.
