A summary of the salutary properties of the strong permanent magnet field sources known as magic spheres is given. Topics of discussion include: obtainable field strengths, field uniformity, field insensitivity to structural modifications, methods of

Certain high‐field permanent magnet structures in the forms of spheroidal and cylindrical shells can be altered so that access ports through specified areas of the shells have minimal detrimental effect on the field integrity in the internal workin

The mass and bulk of the magnetic focusing structures of traveling wave tubes depend greatly on the details of their design. The authors describe several permanent magnet structures that use no iron pole-pieces and depend upon magnetically rigid perm

Both cylindrical (‘‘magic ring’’) and spherical (‘‘magic sphere’’) dipolar permanent magnet field sources are capable of providing arbitrarily high fields in their interior cavities. However, since the obtainable field increases only

The authors show how variations of a magnetic field along a cylindrical or spherical axis are effected for both longitudinal and transverse orientations. Field profiles in cylindrical structures of both orientations and various cross sections (square

A major part of the bulk and mass of an extended interaction amplifier resides in its magnetic field source. Both can be considerably reduced by application of novel designs made possible by high‐energy product permanent magnet materials such as th

The high‐energy rare‐earth permanent magnets afford iron‐free wiggler and twister field sources with greater field strengths in less massive structures than are possible when iron pole pieces and flux conductors are employed. However, the iron

Some electron‐beam devices such as gyro amplifiers are composed of tandem coaxial chambers with different uniform axial magnetic fields in their interiors. Therefore, there is a step in the field profile in the vicinity of the juncture of the two c

A prototype of an iron‐free periodic permanent magnet stack was designed and built to serve as the electron beam focusing element in a traveling‐wave tube. The stack is composed entirely of permanent magnet material and hence has no iron pole pie

Magnetic circuit design has been traditionally difficult because of the usually non-analytic nature of the solutions for fields emanating from arbitrary sources. Further, unlike currents in electric circuits, magnetic fluxes are not neatly confined t
