Cold Model Test of The KOMAC CCDTL Cavities

The Korea Multipurpose Accelerator Complex (KOMAC) project has been initiated to develop and build a high current proton linear accelerator capable of delivering an one GeV cw proton beam with an intensity of 20mA in the final stage. For the first phase of the KOMAC project, a CCDTL (Coupled Cavity Drift Tube Linac) [1, 2] which accelerates 20mA proton beam from 3 MeV to 20 MeV is designed. A cold model cavities are fabricated to check the design, the tuning method, the coupling, and the fabrication methods. The test results will be presented.
