Electromagnetic simulations of the impedance of the LHC injection protection collimator

During the Large Hadron Collider (LHC) 2011 run, significant vacuum and temperature increases were observed at the location of the LHC injection protection collimators (TDI) during the physics fills. Besides, measurements of the LHC transverse tune shift while changing the TDI gap showed that the im...

description During the Large Hadron Collider (LHC) 2011 run, significant vacuum and temperature increases were observed at the location of the LHC injection protection collimators (TDI) during the physics fills. Besides, measurements of the LHC transverse tune shift while changing the TDI gap showed that the impedance of the TDI was significantly higher than the LHC impedance model prediction based on multilayer infinite length theory. This contribution details the electromagnetic simulations performed with a full 3D model of the TDI to obtain both longitudinal and transverse impedances and their comparison with measured observables.
