CONFINEMENT OF PLASMA IN A TRAP WITH A COMBINED MAGNETIC FIELD,
Abstract
The confining properties of an adiabatic trap with a magnetic field increasing in the longitudinal and radial directions are investigated. Such a field is obtained from the combination of a field of the usual mirror configuration and a field of a system of conductors with current, located in parallel to the axis of the trap. On the basis of the results it is concluded that such a field ensures stable confinement of a plasma, not disturbed by magnetohydrodynamic instability. The decay of the plasma is determined by the charge exchange of fast ions on the residual gas; at most the attained times of retention comprise 0.06 sec at p = 7 times 10 to the -9th power mm Hg. A qualitative picture of the distribution of the density of the plasma over the radius of the trap is obtained. (Author)
