Stellarator and Heliotron Devices

This monograph describes plasma physics for magnetic confinement of high temperature plasmas in nonaxisymmetric toroidal magnetic fields or stellarators. The techniques are aimed at controlling nuclear fusion for continuous energy production. While the focus is on the nonaxisymmetric toroidal field, or heliotron, developed at Kyoto University, the physics applies equally to other stellarators and axisymmetric tokamaks. The author covers all aspects of magnetic confinement, formation of magnetic surfaces, magnetohydrodynamic equilibrium and stability, single charged particle confinement, neoclassical transport and plasma heating. He also reviews recent experiments and the prospects for the next generation of devices.

This book systematically introduces plasma physics that will enable nuclear fusion for continous energy production. Especially emphasized is the nonaxissymmetric toroidal field, invented and developed at Kyoto University. All aspects required for the magnetic confinement, formation of magnetic surface, magnetohydrodynamic equilibrium and stability, single charged particle confinement, neoclassical transport and plasma heating are covered. Wakatani also includes experiments and considers the prospects for next generation devices.
