Coupling impedances of LHCb recombination chamber (IR8)

Sumario:The recombination chamber in LHC (Large Hadron Collider) allows the separated beams to merge into the common vacuum chamber surrounding the interaction points. Smooth transitions between pipes of different diameters are achieved with tapers. Parasitic resonances can strongly be attenuated by a continuation of the taper with a planar metal sheet. In this paper we present the numerical estimation of the longitudinal and transverse coupling impedances of the recombination chamber in the LHCb experimental area (IR8).
