Initial experiments on MUSE, a Simple QA-Optimized Stellarator*

MUSE is the first optimized quasi-axisymmetric stellarator and was constructed with permanent magnets, planar TF coils, and additively manufactured support structures.  The construction and assembly was completed in a year. MUSE is optimized for low 3D neoclassical transport, with the effective helical ripple $epsilon_{eff}^{3/2} < 1.e-6  <!--[if supportFields]>lang=EN-GB style='font-size:11.0pt;font-family:Times;mso-fareast-font-family:
