Description
Production, confinement and control of a long static electron column in Gabor-lens device GL2000 were discussed and presented in previous IPAC conferences. Reachable electron densities of about n~2.5*10e14me-3 and single pass ion beam transport with focusing in MeV range were demonstrated in 2025. The present study investigates the possible use of electron plasmas in periodic systems such as synchrotrons, which could be integrated locally to compensate the space charge. Two concepts for electron confinements are considered in comparison. One is the electron lens concept, a dynamic electron plasma (beam) generated by a source and the other one is the Gabor-lens, a static electron plasma achieved by a combination of transversal electric and longitudinal magnetic fields. Challenges in application, main technical features and parameters will be discussed. Studies have shown that it can be assumed, that both systems are promising for the use in periodic accelerator structures to compensate the ion’s space charge in the interaction zone and thereby improve the acceptance and increase the critical space charge limit for an ion beam.
