(a) The beam coupling impedances of a pillbox cavity that is unshielded (solid line) and shielded by a wire cage (dashed line). The inset illustrates the set-up used in CST particle studio to study the impedances (the electron beam propagates in the middle of the system). (b) Dependence of the normalised electric field amplitude on the radius if the beam is shielded. The beam propagates at R = 0 mm, the wires are located at R = 20 mm. The inset illustrates the contour plot of the electric field of the shielded beam.
