Radio frequency (RF) parameters design is an important part in RF system design. In this paper we will introduce a general method of choosing appropriate RF parameters for a circular e+e− collider. The RF parameters are determined with several analytical formulas. With this method, the RF parameters of the Circular Electron–Positron Collider (CEPC) for Conceptual Design Report (CDR) are verified. A new set of RF parameters for the CEPC with 1-cell LG Nb cavities is also designed. Besides, the RF parameters of the CEPC Advanced Partial Double Ring (APDR) and the CEPC Damping Ring (DR) are designed for the first time, and a preliminary study of the beam loading effects of APDR and DR is also carried out.

圆形正负电子对撞机射频参数设计

射频（RF）参数设计是射频系统设计的重要组成部分。在本文中，我们将介绍一种为圆形选择合适的射频参数的一般方法e+e-对撞机。RF 参数由几个分析公式确定。使用这种方法，验证了概念设计报告 (CDR) 的圆形电子-正电子对撞机 (CEPC) 的射频参数。还为具有 1 单元 LG Nb 腔的 CEPC 设计了一组新的 RF 参数。此外，首次设计了CEPC高级部分双环（APDR）和CEPC阻尼环（DR）的射频参数，并对APDR和DR的梁加载效应进行了初步研究。
