Utilization of a superconducting traveling wave accelerating (STWA) structure with small phase advance per cell for future high energy linear colliders may provide accelerating gradient 1.2/1.4 times larger [1] than standing wave structure. However, the STWA structure requires a feedback waveguide [1]. Recent tests of 1.3 GHz model of a single-cell cavity with waveguide feedback demonstrated an accelerating gradient comparable to the gradient in a single-cell ILC-type cavity from the same manufacturer [2]. In the present paper a design for a STWA resonator with a 3-cell accelerating cavity for high gradient tests is considered. Methods to create and support the traveling wave in this structure are discussed. The results of detailed studies of the mechanical and tuning properties of the superconducting resonator with 3-cell traveling wave accelerating structure are also presented.

A new quarter-wave coaxial detachable coupler that preserves the axial symmetry of the cavity geometry and rf field of the 1.3 GHz superconducting cavity has been designed by Euclid Techlabs. A flange with superconducting joint is placed at the zero magnetic field region on the beam tube for the connection between coupler and the cavity. This design also enables processing coupler separately. Update on the engineering design, fabrication process will be reported. The rf test of the coaxial detachable coupler with a single cell cavity is scheduled at the end of 2013.
