- Simulation studies for ion beam extraction systems M.M. Abdelrahman S.G. Zakhary Física, Astronomía y Matemáticas Space Charge Plasma Meniscus Ion Trajectories Ion Beam Emittance The characteristics of the ion beam extracted from an ion sources were investigated using computer code SIMION 3 D Version 7.0. It has been used to evaluate the extraction system in order to produce an ion beam with high current and low beam emittance. The results show that the shape of the extraction electrode plays an important role in ion beam formation. Comparison has been made between two extraction systems, Pierce extraction electrode and spherical extraction electrode. The results show that the spherical extraction system yields ion extraction beam with lower emittance and radius than that the Pierce system. The simulation can provide the basis for optimizing the extraction system and the acceleration gap for ion source. 2009 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46413558005 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.2 Vol.39
