Intense relativistic electron beams were propagated around a 180^∘{} toroidal sector to study beam dynamics in toroidal fields. The major drift was along -→R×→B and no →E×→B drift was observed, in contrast to the case of plasma in toroidal fields. Based on these observations, a method of injection of electron beams into toroidal fields is proposed.
