Confinement of a Cesium Plasma in a Mirror Field

Abstract
Confinement of a thermally‐ionized cesium plasma has been investigated in a magnetic mirror geometry. The mirror ratio R has been varied continuously between 1 and 5.7. The observed confinement of the plasma can be accounted for in terms of resistive diffusion and ion recombination at the end plates of the Q device. ``Bohm'' diffusion appears to be inoperative in the conditions of the experiment.
