# Beam coupling impedances of obstacles protruding into beam pipe

@article{Kurennoy1997BeamCI, title={Beam coupling impedances of obstacles protruding into beam pipe}, author={Sergey S. Kurennoy}, journal={Proceedings of the 1997 Particle Accelerator Conference (Cat. No.97CH36167)}, year={1997}, volume={2}, pages={1732-1734 vol.2} }

The beam coupling impedances of small obstacles protruding inside the vacuum chamber of an accelerator are calculated analytically at frequencies for which the wavelength is large compared to a typical size of the obstacle. Simple formulas for a few important particular cases, including both essentially three-dimensional objects like a post or a mask and axisymmetric irises, are presented. The analytical results are compared and agree with three-dimensional computer simulations. These results…
