Description
Experimental results of the beam transport through a Gabor lens system were not fully understood in the past. The measurement campaign presented at IPAC2013 will be considered as an example with an alternative explanation. Simulation results done by the TraceWin code will be presented and beam impact on the electron column discussed. Especially production of secondary electrons by an ion impact can have massive influence on plasma state and creating waves and instabilities. Additionally, a large scale multi-particles 3D Monte-Carlo-PIC (particle-in-cell) simulations with electrons and ions were carried out. Goal was to understand collective phenomena in non-neutral plasma generated by passing beam in various scenarios. Up to $10^7$ macroparticles were implemented in parallel processing on 50 processors of the FUCHS Cluster. Possible influence on the focusing properties and imaging quality will be evaluated and the dependence on time scale and ion beam energy discussed. Simulation results will be presented with an impact on future designs.
