Abstract

The main goal of this work was to experimentally check the value of the "cos+lin" method previously developed by the authors. The design and optimization of the beam extraction optics for a hollow-cathode ion source have been carried out. Starting from an existing electrode arrangement the optical system (e.g., the shape and potential of the electrodes) was gradually fitted to the requirements of the model. The final optimization of the optics was carried out by the SIMION computer code. We tested the extraction and focusing optics with H+ and Ar+ ions at different energies up to 30 keV. The electrode potentials, optimized for the best beam parameters (the largest intensity and smallest diameter), are in good agreement with the calculated values.
