A new helical axis stellerator called Helias-Heliac Hybrid Stellerator (HHHS) is based on the modulated l = 1 helical coil. In order to obtain Helias-like and Heliac-like configurations, toroidal coils, poloidal coils and an additional l = 1 helical coil are adjusted to control magnetic field spectrum. It is shown that the bumpy field with opposite sign to l = 1 helical field is essential to minimize the neoclassical ripple transport. An HHHS configuration with sufficient magnetic well and reduced neoclassical ripple transport is demonstrated. 11 refs., 6 figs., 2 tabs.
