【摘要】 为缩短边耦合加速腔腔片制造周期，需用部分腔片确定Ｔａｕｋ的π／２模式频率，采用整腔结尾，调节端腔频率使相邻耦合腔输出最小的方法，得到比较准确的结果。焊后调谐，耦合腔频率用近似方法调节，加速腔则用相对精确的方法调谐。用桥耦合器连接Ｔａｎｋ后，腔数增加引起π／２模式频率下降，桥耦合器的频率要调高于设计值。更多还原

【Abstract】 AbstractWhen we tuned Coupled-Cavity Linac tanks for SSC,we used two tunable aluminum endcells and eight segments to determine the frequency of π/2 mode of a tank.Tuned the aluminumend cells until the RF signals pick up from the side coupled cavities neighboring end acceleratingcavities became minimum. Thef_π/2 of this cavity chain is regarded as the f_π/2of the tank.Afterbeing brazed,the coupled cavities are approximately tuned and the accelerating cavities areaccurately tuned.When tanks are connected with bridge couplers,f_π/2of the module is lower thanthat of designed.RF tuning procedure is discussed and typical results are given in this thesis.更多还原
