Discusses the generation of an electron beam by a hollow cathode gun in a cusp magnetic field. Proposal of such a gun for an electron cooling device without toroids; Beam's experience of a disturbance region near the axis where the electron temperature becomes higher; Conditions for generating the beam so as to restrict the extent of the region as much as possible.
