	The commissioning of the superconducting (sc) continuous wave (cw) LINAC Demonstrator, financed by the Helmholtz Institute Mainz (HIM) mainly, is planned in 2014. The aim is a “full performance test” at GSI-High Charge Injector (HLI) of a 217 MHz sc CH-Cavity, which is designed by the Institute of Applied Physics (IAP) of the University Frankfurt. Inside the cryostat a suspended frame supports the cavity embedded by two solenoids. All of these components are in fabrication. The testing environment is about to be completed. The radiation protection bunker, and the beam transport line straightforward to the GSI-HLI, comprising beam diagnostic components as well as focusing and steering magnets, has been mounted.

	Funding: GSI, BMBF Contr. No. 06FY7102, 06FY9089I At the Institute for Applied Physics (IAP), Frankfurt University, a sc 325 MHz CH-Cavity has been designed and built. This 7-cell cavity has a geometrical beta of 0.16 corresponding to a beam energy of 11.4 AMeV. The design gradient is 5 MV/m. Novel features of this resonator are a compact design, low peak fields, easy surface processing and high power coupling. After successful tests at Research Instruments (RI) and in Frankfurt the cavity was processed and cleaned at RI and power tests at 4K have been performed at the cryo lab in Frankfurt. In this paper these measurements will be presented.
