This study focuses on the mechanical analysis, impedance calculations, and leak rate tests of the special flange with low-impedance structure used in cERL. The finite element method (FEM) is applied to get the stress and deformation information of the flange. The leak rate tests have been carried out to investigate the vacuum properties of this special flange. The results can help to understand the sealing mechanism and to optimize the structure of the flange for better vacuum and impedance performance in the future.
