Abstract

TWIST is a simple computer model of reactor scale stellarator devices. It allows determination of parameter sets which optimize given objective functions and simultaneously take into account any constraints which may be imposed on any of the model variables. The model is based on equations describing the geometrical arrangement, together with the plasma, blanket, shield, and magnet system. Typically, constraints are imposed on the ignition margin, first wall loads, neutron fluence, coil current density, maximum magnetic induction at the coils, coil tensile stress, neutron dose to the magnets, and dpa's and helium concentration in the first wall material. The application of TWIST is demonstrated in sample calculations for reactor scale devices based on magnetic field configurations of the Wendelstein VII-AS type.
