Description
The collisionless dynamic of ions in the axisymmetric diamagnetic trap is discussed in the report. Smallness of magnetic field leads to non-conservation of magnetic moment of ions. It can results in chaotic movement and fast losses of ions. Two mechanisms allowing ions to confine in the trap unlimited time (if Coulomb collisions and instabilities are neglected): conservation of adiabatic invariant if magnetic field is smooth enough and so-called absolute confinement of ions having large azimuthal velocity. So there are different regimes of plasma confinement in the diamagnetic trap. This regimes and requirements to magnetic system of the trap are discussed.
