Description
D-Pace is investigating the development of a 13.56 MHz RF-driven ion source for the production of negative ion beams. The ion source employs a hybrid design that combines features of the TRIUMF-licensed filament ion source and the RADIS ion source licensed from the University of Jyväskylä. The present work focuses on experimental studies aimed at improving the long-term beam current stability and overall operational performance of the RF ion source.
Experiments were conducted to evaluate the influence of plasma chamber surface materials and RF operating conditions on ion source performance. In particular, different plasma-facing materials were investigated to assess their effects on the extracted beam current stability. In parallel, a modified RF impedance-matching configuration was developed and tested to improve RF power coupling and reduce operational instabilities. Initial investigations of an internal RF antenna configuration were also carried out, and the first operational results are presented.
