Impedance measurements for the pumping holes in the LHC liner
Creators
- 1. European Organization for Nuclear Research, Geneva (Switzerland)
Description
Results of impedance measurements, performed by the triaxial wire method, on a 2 m long model of the LHC vacuum chamber are presented. The model consists of an inner screen (liner) with pumping holes and of the outer vacuum chamber. The transmission coefficient for different numbers of holes with various radii confirms the role played by TEM modes, propagating at the same speed of the beam particles in the coaxial structure formed by the liner and the outer vacuum chamber. The results of these measurements are compared to analytical estimates of the coupling impedance. (author) 7 refs.; 1 fig.; 1 tab
