| Abstract |
The GSI UNILAC will serve as the main injector for the upcoming FAIR project. Since the existing Alvarez DTL is in operation for more than 40 years, it has to be replaced to ensure reliable operation in the future. To this purpose a compact and efficient linac design based on IH-type cavities and KONUS beam dynamics has been designed at IAP Frankfurt*. It consists of five 10⁸ MHz IH-type cavities that can be operated by the existing UNILAC RF amplifier structure. The transversal focusing scheme is based on magnetic quadrupole triplet lenses. The optimized design provides full transmission and low emittance growth for the design current of 15 emA U²⁸⁺ accelerating the beam from 1.4 MeV/u to 11.4 MeV/u. Extensive error studies were performed to define tolerances and verify the stability of the design with respect to misalignment and injection parameters. The design provides a compact and cost efficient alternative to a new Alvarez linac. With a total length of just 22.8 meters it will leave room for future energy upgrades in the UNILAC tunnel.
