Propagation and focussing of high current relativistic electron beams in dielectric channels

The development of effective transport and focussing methods for high current relativistic electron beams (REB) is of great importance for the use of such beams in controlled fusion experiments with inertial containment, in microwave generation etc. REB propagation for considerable distances is possible when the beam is contained by external magnetic fields or when it is neutralized by the REB proper fields in a medium that does not inhibit transport.
