Abstract
It is shown that potato orbits in the near-axis region of a high beta tokam ak are squeezed in a magnetic well. The squeezing factor is the same as tha t for the banana orbits derived in an earlier work [Phys. Plasmas 3, 2843 ( 1996)]. It depends on the energy of the particle. For high-energy particles , the size of the squeezed orbits is independent of their energy. This impl ies improved confinement for high-energy particles and for high beta tokama ks with advanced fuels. (C) 2001 American Institute of Physics.
