New compact ion source design and implementation for low current applications

Abstract

A new compact electron cyclotron resonance (ECR) ion source for low current applications, designed and built in-house at the University of the Basque Country (UPV/EHU) is presented. The source was designed to use as many commercially available components as possible for key tasks such as electromagnetic resonators, magnetic structure, RF power couplers and beam transport, to lower the cost and lessen reliance on specially made parts for spares. This leads to a cost-effective yet compact and fully functional design. The main design decisions are described and experiments on plasma generation and the proton beam extracted using the source are shown and discussed.
