Abstract :
The paper presents a design of a W-band planar accelerating structure (muffin tin). The structure is a 2 π/3-mode traveling wave, constant impedance structure with an operating frequency of 91.392 GHz. The design includes a new power coupler and a cavity geometry optimized for high shunt impedance. A 7-cell cold test prototype has been fabricated by wire electro discharge machining. Measurements were performed with a scalar network analyzer for both S-parameters and bead pull measurements. The RF parameters and measured results are presented and compared with the numerical results obtained by GdfidL simulations
