THE FRANKFURT FUNNELING EXPERIMENT*

The Frankfurt Funneling Experiment is a scaled model of the first funneling stage of a HIF driver to study the funneling technique. Funneling is a procedure to multiply beam currents at low energies in several stages. In each stage two beam lines are combined into a common beam line. The funneling technique is required for new proposed high current accelerator facilities like HIDIF. The main goal is to prevent emittance growth during the funneling process. Our experiment consists of two ion sources, a Two-Beam RFQ accelerator, a funneling deflector and a beam diagnostic system. We have funneled two beams to a single beam, but the measurements have shown a bad matching of the RFQ to the funneling deflector. With our new RFQ electrode design we achieve a special three dimensional matching to the deflector. The results of our measurements and simulations will be presented
