TL;DR: In this article, a new type of damped detuned structure with optimized round-shaped cavities (RDDS) was proposed for X-band accelerator structures for the JLC/NLC linear collider.

TL;DR: In this paper, the authors developed a new type of damped detuned accelerator structure with optimized round-shaped cavities (RDDS), and discussed some important R&D aspects of the first structure in this series.

TL;DR: The accelerator structure groups for NLC (Next Linear Collider) and GLC (Global Linear Colliders) have successfully collaborated on the research and development of a major series of advanced accelerator structures based on room-temperature technology at Xband frequency.

TL;DR: The NLC and JLC groups face two major challenges in designing X-band accelerator structures for an electron-positron linear collider as mentioned in this paper, the first is to demonstrate stable, long-term operation at a 70 MV/m gradient, which is required to keep the machine cost low, and the second is to strongly suppress the structure long-range wakefield, required to achieve high luminosity.
