TI - A Superconducting 217 MHz Single Spoke Cavity for the Helmholtz Linear Accelerator at GSI J2 - Proc. of LINAC2022, Liverpool, UK, 28 August-02 September 2022 CY - Liverpool, UK T2 - International Linear Accelerator Conference T3 - 31 LA - english AB - A new superconducting (SC) continuous wave (CW) linac, providing high efficient heavy ion acceleration above the coulomb barrier, is going to be built at GSI to fulfill the upcoming demands in the research field of super heavy element (SHE) synthesis. The so called HELIAC (HElmholtz LInear ACcelerator) delivers ion beams in the energy range of 3.5 MeV/u and 7.3 MeV/u with a mass to charge ratio (A/z) of up to 6. Superconducting multi-gap crossbar-H-mode (CH) cavities with a resonance frequency of 217 MHz are used for beam acceleration. In addition, SC single spoke buncher cavities should ensure longitudinal beam matching to the corresponding CH sections. Therefore, the first 217 MHz single spoke cavity with beta 0.07 has been developed at HIM/GSI and built at an industrial partner. In this paper the design of the cavity and first RF measurements during manufacturing are presented.
