Bench Measurements and Simulations of Beam Coupling Impedance

Uwe Niedermayer

Abstract


After a general introduction, the basic principles of wake-field and beamcoupling-impedance computations are explained. This includes time domain, frequency domain, and methods that do not include excitations by means of a particle beam. The second part of this paper deals with radio frequency bench measurements of beam coupling impedances. The general procedure of the wire measurement is explained, and its features and limitations are discussed.


Keywords
