A condition for absolute confinement of alpha particles in helical tokamaks

K. Ikuta, C.G. Gimblett1978年被引用 4Nuclear FusionIF 3出版社

The criterion for absolute confinement of alpha particles in helically symmetric magnetic field configurations is established. In particular, a helically deformed tokamak configuration is investigated. The helical deformation of the magnetic surfaces can significantly increase the value of the product aB0 required for absolute confinement of alpha particles, where a is the characteristic plasma cross-section in metres and B0 is the characteristic field strength in teslas.
