Abstract
The secondary electrons in an electron cooling system determine the cu rrent losses [1]. Their parameters depend on the collector efficiency. In this paper the behaviour of the secondary electrons in the LEAR el ectron cooler with S-shaped bending toroid magnets is examined. The se cond problem which takes place with secondary electrons is related to the generation of neutralised electron beams in an electron cooling sy stem [2]. The generation of very dense neutralised beams is restricted by the beam-drift instability. This is a convective instability appea ring in stationary conditions due to the feedback created by secondary electrons.
