Design of cepc superconducting rf system
WebJul 5, 2024 · The HOM couplers in the 3.9 GHz cavity are of the coaxial type and have two basic functions: 1) rejecting the fundamental mode and 2) extracting the HOM energy over a broad frequency band. The rejection of the accelerating mode can be fulfilled by tuning the HOM notch filter, as illustrated in Fig. 8 a. WebOct 11, 2024 · This is the first in-house developed 499.8 MHz HOM-damped superconducting cavity system in China. The design, fabrication, post processing and tests of the niobium bare cavity and its auxiliaries, as well as the horizontal high-power test of the cavity system are presented. Introduction
