Optimisation of N=6 Helias-Type Stellarator
Collision-less particle confinement in stellarator configurations in which the lines of the magnetic field strength Best=const lie on a helical path on the magnetic surfaces is investigated numerically for a six-period system. The optimisation is performed with different penalty functions that are connected with the pseudo symmetry condition and the condition that the second adiabatic invariant J(II) forms closed contours. In addition, the effect of Î on the particle confinement is studied.
