Abstract

Recently, there is an increasing need for H2+H_{2}^+ and H3+H_{3}^+ ion sources. One example are ion therapy facilities, where C4+C^{4+} and H3+H_{3}^+ ion beams along the linac are of great interest. Another example is a H2+H_{2}^+ test beam for linacs finally operated with intense deuteron beams. At Frankfurt, a simple proton ion source is needed to test a new kind of beam injection into a magnetic storage ring\cite{EPAC08}\cite{EPAC06}. This article describes a volume type ion source which can deliver upto 3.05 mA3.05~mA beam current at 10 keV10~keV in stable dc operation. It is a hot filament driven ion source which can provide high fractions of pp, H2+H_{2}^+ or H3+H_{3}^+, depending on the operation settings.
