Beta-beating in the effective model of the LHC using PTC

An effective model of the LHC optics has been developed based on measurements of magnetic field, alignment errors and closed orbit. This model utilizes the Polymorphic Tracking Code, with MAD-X as a front-end, to allow the inclusion of harmonics to arbitrary order in thick lattice elements. Beta-bea...

Sumario:An effective model of the LHC optics has been developed based on measurements of magnetic field, alignment errors and closed orbit. This model utilizes the Polymorphic Tracking Code, with MAD-X as a front-end, to allow the inclusion of harmonics to arbitrary order in thick lattice elements. Beta-beating calculations have been performed with this model at injection optics and at 3.5 TeV with squeezed optics (Beta=3.5 m at the interaction point) The model predictions are in good agreement with the measurements performed in the 2010 LHC commissioning run.
