Higher-order Mode Analysis of 9-cell TESLA Superconducting Accelerating Cavity

Qin Jiang, Rui Zhang, Yong Wang, Zhi-Hui Geng

Open publisher page 1 citations

Abstract

The high-energy particle accelerator uses the fundamental mode of the superconducting radio frequency cavity to accelerate the charged particle beam, and when the charged particle beam passes through the radio frequency(RF) cavity, it will excite a series of harmful higher-order modes(HOMs) besides the fundamental mode. The 3D simulation software is used for 9-cell TESLA superconducting acceleration cavity HOM simulation calculation. Analyze the mode spectrum distribution of each HOM and the performance parameters that characterize the HOM, and identify harmful HOMs.
