Quasi-Symmetry in Stellarator Research 5. Status of Physics Design of Quasi-Axisymmetric Stellarators 5.3 Comparison of Physics Designs between NCSX and CHS-qa

摘要

Physics designs of NCSX and CHS-qa are compared. Although those are basically of similarmagnetic configuration the important difference is in the role of the bootstrap current. Different toroidal period numbers make the aspect ratio and the machine design different.
