Abstract :
Funneling is a procedure to multiply beam currents at low energies in several stages. The Frankfurt funneling experiment is a prototype of such a stage. Our experiment consists of two ion sources, a two-beam RFQ accelerator, a funneling deflector and a beam diagnostic system. The two beams from the ion sources are injected into two RFQ beam lines. These two beams are accelerated in a two-beam RFQ and combined to one beam axis with a funneling deflector. The last parts of the RFQ electrodes have been replaced to achieve a 3d focus at the crossing point of the two beam axis. The newly designed multigap deflector is adapted to the optimized funneling section. First results and measurements with the new setup will be presented.
