The purpose of the project is to investigate how the pre-sent ion source could be replaced by a P.I.G. cold cathodes one with a longer lifetime. Experiments de-scribed in this article were done on a dedicated test setup to benchmark the different modes. A new chimney design has been developed to test cold cath-ode mode in CYCLONE®230 without any other me-chanical modifications.
