Characterization of volume type ion source for $p$, $H_2^{+}$ and $H_3^{+}$ beams

Abstract

Recently, there is an increasing need for $H_2^{+}$ and $H_3^{+}$ ion sources. One example are ion therapy facilities, where $C^{4+}$ and $H_3^{+}$ ion beams along the linac are of great interest. Another example is a $H_2^{+}$ 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 $3.05mA$ beam current at $10keV$ in stable dc operation. It is a hot filament driven ion source which can provide high fractions of $p$, $H_2^{+}$ or $H_3^{+}$, depending on the operation settings.
