At the Lawrence Berkeley National Laboratory we are constructing an ECR ion source test facility for nuclear science as well as industrial applications experiments. For these purposes, a single-stage 2.45 GHz electron cyclotron resonance ion source has been designed and constructed. It features an axial magnetic field with a mirror ratio of up to six and a hexapole field produced by a simple Nd{endash}Fe{endash}B permanent magnet assembly. In order to enhance the ion confinement time, the source plasma volume has been enlarged as much as possible while still maintaining a high mirror ratio. This paper describes the design of the ion source, the extraction system and the test stand. First, operational experience and experimental results with an argon discharge are presented. {copyright} {ital 1998 American Institute of Physics.}
