This means that the ions (typically radioactive ions produced via the ISOL method) have to be extracted from a source at a terminal voltage in excess of 60 kV. Presently the ISAC target modules cannot hold more than 54 kV (and some lower than this) so that some of the higher masses cannot be successfully accelerated. A small 3-gap RF structure at 11.8 MHz has been designed to provide an energy matching to the RFQ. The structure operates in pi-mode and provides a maximum effective accelerating voltage of 16 kV to the low energy ions. Beam dynamics considerations, RF and mechanical design will be described. First results of RF tests of the structure will be given.
