Abstract:
Problems of interaction and thermalization of colliding plasmas characterized by large axial velocities and generated with strong induced magnetic dipole moments were studied. Experiments were conducted in two configurations in which the plasma was generated, compressed, and accelerated by the same magnetic field. The geometry consists basically of two asymmetric collapse accelerators compounded electrically. Two possible configurations exist 1 the currents in both halves circulate in the same sense which is called Helmholtz geometry and 2 the currents in the two parts will have opposite directions and are termed a counter Helmholtz geometry. The gas, usually hydrogen, is contained in a biconical quartz container. The geometries are connected to low-inductance capacitor banks and special vacuum switches are used for current transfer. A plasma sheath is thus generated at a precise radial within each of the two halves of the geometry. The plasma appears to have slightly elongated shapes. In the interior both ions and electrons will be mainly non-adiabatic and are bounded by interval collision with the sheath.
