| Abstract |
The interaction between electrons and positive ion beams and its application in accelerator physics are investigated. A space charge lens named Gabor lens was developed which confines electrons in a static column by external fields. The confined electrons are used for focusing and may support space charge compensation. In this structure the relative velocity between the ions and the electrons is maximal and corresponds to the beam velocity. An electron lens as at the Tevatron* is operated with a lower relative velocity in order to compensate the beam, to clean the beam abort gap or to excite the beam for beam dynamics measurements. In comparison electron cooling needs the same velocity of the ion and the electron beam. The following study contains the superposition of electric and magnetic self-fields and their impact on the density distribution of the ion beam and of the electron beam. Recombinations and ionisations are neglected. This is the beginning of an interface between these topics to find differences and similarities of the interaction between ions and electrons with different relative velocities. This may open up opportunities e.g. for the diagnostics of particle beams.
