Abstract

The production of high-current beams is a key point for different applications and the importance ofthis role is deemed to increase in the coming years, both for industrial applications and for research projects. High-current and high-brightness H+ beams can be provided by 2.45GHz MDIS --Microwave Discharge Ion Sources--, which presents many advantages in terms of compactness, high reliability, ability to operate in CW mode or in pulsed mode, reproducibility, and low maintenance. A detail characterization of two MDIS, VIS and SILHI is reported here: for each source the most important parameterwas measured and analyzed. Special attention was paid to improve the performance of the source, increasing the electron density for a more efficient ionization; as a consequence, studies to optimize the extracted current have been carried out. A series of measurements have been realized with the VIS source by inserting a thick Al2O3 tube inside the plasma chamber (passive technique) and an innovative mechanisms of plasma ignition based on electrostatic waves (ESW) was proved with a plasma reactor.
