A principal objective of controlled, thermonuclear fusion research has been the stable confinement of a hydrogen plasma. Material containers are not suitable, but magnetic fields are known to exert strong forces on the electrically charged particles of a plasma. A cusped field, increasing in all directions away from the plasma (creating a magnetic well), has been found to be most favorable for confinement, as was experimentally demonstrated by Ioffe [1] in 1961 with a mirror-pair and a superimposed hexapole.
