High-gradient linacs of next generation require novel accelerating structures which are compact, robust and cost-effective. Dedicated research and development have been launched in the linear-collider community. This paper focuses on the technological developments directed to show the viability of novel welding techniques and related applications, in order to benefit from the superior high-gradient performance of accelerating structures made of hard-copper alloys. The structure geometry that we propose allows getting a high longitudinal shunt impedance of the accelerating mode and increasing the mode separation frequencies.
