A Cell-Coupled Drift Tube Linac (CCDTL) accelerating structure at 352 MHz has been selected for the energy range 40 to 90 MeV of Linac4, a new injector linac for the CERN accelerator complex. With regard to a conventional DTL in this energy range this structure presents the advantages of lower construction cost and easier access, cooling and alignment of the focusing quadrupoles placed between tanks. A full-scale high-power prototype of about 1/3 of a complete module has been designed and built at CERN. It is fed by a waveguide input coupler of novel conception. This paper summarizes the main mechanical features of the prototype and reports the results of low-power and high-power RF testing.
