To demonstrate the operation ability of superconducting (s.c.) CH cavity technology two structures of this type are under development at the Institute for Applied Physics (IAP) of Frankfurt University. The construction of a s.c. 325 MHz CH cavity with 7 cells and an envisaged design gradient of 5 MV/m is finished and will be tested in the next months under cryogenic conditions with full RF power.
Furthermore, the production study of a 217 MHz CH structure with 15 accelerating cells and a design gradient of 5.1 MV/m is finished. This cavity will serve as demonstrator for the planned s.c. cw LINAC at GSI. The proposed cw LINAC is highly requested to fulfil the requirements of nuclear chemistry and especially for a competitive production of new Super Heavy Elements (SHE) in future. A full performance test by injecting and accelerating a beam from the GSI High Charge Injector (HLI) is planned in 2013/14.
The current status of both s.c. CH cavities is presented.
