Physics studies are carried out on heliotron/torsatron plasmas concentraring on the Large Helical Device (LHD). Flexibility and freedom of LHD as an experimental device are emphasized. A variety of configurations can be realized changing the pitch parameter and the poloidal fields. The possibilities to reduce the bootstrap current and to enhance the radial electric field are investigated.
