Divertor heat load distributions due to thermal and alpha particles have been assessed in an NCSX-based compact stellarator reactor. A divertor plate system is envisaged, with 4 plates per field period and covering 7% of the plasma surface area. The field-line tracing technique is employed; for thermal flux, the conventional approach is used, while for alphas, their characteristic exit pattern from...
Divertor heat load evaluation studies are being carried out for an example compact stellarator reactor configuration modeled after the National Compact Stellarator Experiment (NCSX). Using the field line tracing technique, an initial divertor plate geometry has been obtained, with one plate per field period, which covers 15% of the plasma surface area. A plate heat load peaking factor of 14 is acceptable...
Injection of massive quantities of deuterium or noble gases (>1022 molecules) has proven to be very effective at mitigating the deleterious effects of disruptions in the DIII-D tokamak. Both the heat load to the divertor and the halo current forces to the first wall were reduced by more than a factor of four. Total electron densities (free and bound) of ~1021 m-3 have been achieved, close to densities...
