Abstract
A periodic permanent magnet stack comprises a plurality of aligned, juxtaed, hollow hemispherical flux sources each of which produces a uniform high-field in its hemispherical central cavity. The magnetic field orientations in the central cavities are axially directed and alternate or reverse in direction from hemisphere to hemisphere. An axial bore hole through the stack provides a continuous channel or path through which a beam of charged particles will travel.

A periodic permanent magnet structure comprising a plurality of aligned juxtaposed hollow hemispherical flux sources each of which produces a uniform high-field in its hemispherical central cavity, the magnetic field orientations in the central cavities being axially directed and successively alternating in direction from hemispherical source to hemispherical source, and an axial bore hole through the magnetic poles of the stack of hemispheric flux sources so as to form with said cavities a continuous channel through the stack through which a beam of charged particles can travel.
