| Summary: | Theoretical and experimental work on electron beams which are produced by a magnetically shielded electron gun and are maintained by an axially symmetric magnetic field is described. Such electron beams are commonly termed to be "magnetically focused". Three additions to the earlier theories are presented. Thermal velocity considerations have led to a formula which gives a lower limit to the flux density for maintenance of a magnetically focused beam within a specified radius. The effect of a misalignment between the beam and magnetic field on the required flux density has also been considered. |
