Results of an optimization toward quasi‐isodynamicity for a stellarator with a comparatively large number of periods, N = 12, are presented. The following set of physics properties to be achieved was used: 1) good long‐time collisionless confinement of α‐particles; 2) small neoclassical transport in the 1/ν regime; 3) small bootstrap current; 4) high stability‐β limit. As a result, the boundary magnetic surface of a configuration is found that satisfies the above requirements for 〈β〉 ≈ 20%.
