Testing and optimization of an ion source

A thorough description of the testing of a saddle-field ion source is presented in the diploma thesis. The most important experimental results, such as Faraday cup measurements of the ion beam current profile and of the ion energy spectra, are included. Based on these results it is shown that the optimized ion source works correctly and according to the expectations. At the end of the thesis, the development of the ion-optical and construction design of the focusing optics is described. The manufactured optics assembly attached to the ion source is also shown
