Abstract

Summary form only given. We investigated the interaction of an ion beam with a free electron target. The free electrons are produced in a pseudospark discharge. Through a hole in the anode a high energy electron beam is emitted. By applying different discharge voltages (10-30 kV) the electron beam energy can be varied. The influence of the discharge current and the gas pressure on the interaction properties is investigated. Electron density and temperature of the discharge are conceived from spectroscopy. With these experiments we want to determine the best operational parameters to obtain the highest possible stripping efficiency. The device is tested at the tandem accelerator in Erlangen with different ion species. We used a Monte Carlo simulation to estimate the experimental measurements.
