    "abstract": "New high current accelerator facilities like proposed for HIDIF or ESS\nrequire a beam with a high brilliance. These beams can not be produced by a\nsingle pass rf-linac. The increase in brightness in such a driver linac is done\nby several funneling stages at low energies, in which two identically bunched\nion beams are combined into a single beam with twice the frequency current and\nbrightness. Our Two-Beam-RFQ funneling experiment is a setup of two ion\nsources, a two beam RFQ, a funnel deflector and beam diagnostic equipment to\ndemonstrate funneling of ion beams as a model for the first funneling stage of\na HIIF driver. The progress of the funneling experiment and results of\nsimulations will be presented.",
