Abstract :
High intensity accelerator concepts for Heavy Ion Inertial Fusion (HIIF) injectors require small emittance, high current and high energy beams. The improvement of 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. For the Heavy-Ion Driven Ignition Facility (HIDIF) we have proposed the use of a two-beam accelerator structure which provides two beams within one cavity and a single RF deflector structure which bends the two beams to one common axis. The progress of the experiment and first beam-test results are presented
