Abstract
The effective ripple is analysed for the final version of the quasi-axisymmetric stellarator configuration with a low aspect ratio, CHS-qa. For the computation, a method is used that is based on the integration along magnetic field lines in a given magnetic field. Computations are done for magnetic fields presented in Boozer magnetic coordinates as well as for magnetic fields produced directly by currents in the modular coils of the device. The computations show the significant advantage of CHS-qa over a conventional stellarator resulting from the reduced effective ripple.Keywords
