Development and Investigations of Coupling-Antenna Geometries at the S-DALINAC* — •C. Brückmann, M. Arnold, T. Bahlo, R. Grewe, N. Pietralla, and M. Steinhorst — Institute for Nuclear Physics, TU Darmstadt, Germany

The thrice-recirculating superconducting linear accelerator S-DALINAC [1] is the central research instrument of the Institute for Nuclear Phyics at TU Darmstadt. It is operated in cw-mode at a frequency of 3 GHz using superconducting niobium structures for acceleration. After the first commissioning in 1989 the rf couplers have been redesigned and replaced. The current operational setup uses a specific antenna geometry to couple to the rf field of the cavity. Investigations on other geometries of the input coupler antennas regarding their coupling behaviour and electric field profile for a possible upgrade of the antennas are ongoing. The results of these investigations will be presented.
