Description
A quasi-traveling-wave parallel-coupled (TWPC) accelerating structure is proposed for compact linacs requiring both high RF efficiency and improved frequency tolerance. In contrast to conventional standing-wave parallel-coupled structures, the proposed topology enables partial reflected power generated under detuned conditions to be redistributed through the feeding manifold and reabsorbed by downstream cavities. A 12-cell x-band TWPC structure operating in the $5\pi/6$ mode was designed using a cascaded waveguide feeding network. The structure achieves approximately 95\% unloaded RF power utilization with a 1.8 MW input power level. Beam dynamics simulations predict a 5 MeV energy gain with a 95%-bandwidth of 1.4 MHz.
