  Use of a traveling wave (TW) accelerating structure with a small phase advance per cell rather than a standing wave structure may provide a significant increase of the accelerating gradient in superconducting linacs. For the same surface electric and magnetic fields the TW achieves an accelerating gradient 1.2/1.4 larger than TESLA-like standing wave cavities [1]. Recent tests of L-band model of a single-cell cavity with waveguide feedback [2] demonstrated an accelerating gradient comparable to the gradient in a single-cell ILC-type cavity from the same manufacturer. This article presents the next stage of development of the TW resonance ring with 3-cell accelerating cavity which supposed to test in traveling wave regime. The main simulation results of the microphonics and Lorentz force detuning are also considered.
