On trapped modes in the LHC recombination chambers: experimental results.

The recombination chamber allows the separated beams to merge into the common vacuum chamber surrounding the interactions points. Smooth transitions between pipes of different diameters are achieved with tapers. Previous numerical studies have found a potentially harmful trapped mode which can be at...

description The recombination chamber allows the separated beams to merge into the common vacuum chamber surrounding the interactions points. Smooth transitions between pipes of different diameters are achieved with tapers. Previous numerical studies have found a potentially harmful trapped mode which can be attenuated by a continuation of the taper with a planar metal sheet. In this paper we compare these numerical results against bench measurements on a simple scaled prototype of the recombination chamber with rectangular cross-sections.
