This work aims to analyse the tolerances given by two effects on the performance of the travelling-wave accelerating structure: the reflection along the structure and the change in the nominal accelerating voltage, which is essential for the projects with a large number of accelerating structures. The detuning and dephasing caused by systematic temperature shifts, systematic geometric errors and random geometric errors has been investigated in this paper. RF parameters of travelling-wave accelerating structure CLIC-K designed for klystron-based first stage of CLIC is used to defining the fabrication shape accuracy specification as well as the working temperature control for the high-gradient structurer if tuning is unfeasible.

这项工作旨在分析对行波加速结构的性能产生两个影响的容差：沿结构的反射和额定加速电压的变化，这对于具有大量加速结构的项目至关重要。本文研究了由系统温度变化，系统几何误差和随机几何误差引起的失谐和相移。为基于速调管的第一阶段的CLIC设计的行波加速结构CLIC-K的RF参数用于定义制造形状精度规格以及在无法进行调整的情况下用于高梯度结构体的工作温度控制。
