Abstract :
Funneling is a procedure to multiply beam currents at low energies which is necessary for the proposed new high current accelerator facilities like HIDIF or ESS. Funneling can be done by several stages. The beams of several LEBT´s are merged in multiple stages to any kind of energy and beam current by funneling. The main goal is to keep the emittance nearly unchanged. The Frankfurt funneling experiment consists of two ion sources, a two-beam RFQ accelerator, two different funneling deflectors and a beam diagnostic equipment system. The whole set-up is scaled in He+ instead of Bi+ of the first funneling stage of a HIIF driver. The progress of our experiment and the results of the simulations will be presented.
