Abstract
Confinement of charged particles by axially symmetrical, stationary magnetic fields and electric fields is discussed. It is shown that if the coil connections are made as small as possible and if the magnetic field, in the neighborhood of the connections, from the supply current predominates over the field from the coil, particles will be reflected and will not be absorbed by the connections. The field from the supply current gives an additional drift in planes through the z axis, but since the connections carry current in opposite radial directions, a cancellation of the drift takes place for particles passing around the z axis repeatedly.
