Abstract：
The Disk and Washer (DAW) accelerating structure not only has shunt impedance and high Q value,but also has a high coupling constant between the neighboring cells. At X band,its advantages are especially useful. In this work, a mathematical model used to optimize DAW (without supports) cavities by SUPERFISH was built and the solution was presented. Moreover,the optimization of DAW (with supports) by MAFIA400 was also carried out and the influence of supports was analyzed.
The dispersion curve of the optimized DAW cavities was calculated by URMELT (without supports) and MAFIA400 (with supports),the influence of the supports was studied,and the problem of the overlapping of passband in the accelerating frequency was discussed.
