New high current accelerator facilities like proposed for HIDIF or ESS require a beam with a high brilliance. These beams can't be produced by a single pass linac. The increase in brightness in such a driver linac is done by several funneling stages at low energies, in which two identically bunched ion beams are combined into a single beam with twice the frequency, current and brightness. Our Two-Beam-RFQ Funneling Experiment is a setup of two ion sources, a two beam RFQ, a funnel deflector and beam diagnostic equipment to demonstrate funneling of ion beams as a model for the first funneling stage of a HIIF driver. The progress of the funneling experiment and results of simulations will be presented.
