Abstract
A Cell-Coupled Drift Tube Linac (CCDTL) accelerating structure at 352 MHz has been adopted for the energy range 40 to 90 MeV of Linac4, the new 160 MeV 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 representing 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 RF tuning procedure and the results of high-power RF testing.Contribution to the APAC 07, Indore (India) Work supported by the European Community-Research Infrastructure Activity
