There is a possibility of enhanced plasma confinement in axially symmetric linear traps due to significant modification of equilibrium close to the upper beta limit. In general this type of equilibrium is highly unstable to ballooning modes while its low internal magnetic field may cause non-adiabatic particle losses. However, under special conditions these problems can be probably overcome....

The recently proposed diamagnetic confinement (DC) mode (diamagnetic “bubble”) is designed to increase plasma parameters in open traps due to a significant increase in confinement time. We constructed a numerical stationary model of the diamagnetic “bubble” equilibrium in an axisymmetric open trap. The theoretical model is based on the Grad-Shafranov equilibrium equation and plasma transport...

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...

The formation of high beta plasma by means of neutral beam injection was studied. Energy balance was treated to obtain the scaling of threshold power of the beams required to form high beta equilibrium.
