Abstract : This patent application discloses a periodic permanent magnet stack comprises 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 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. (jhd)
