Beam-Gas Imaging at the LHCb experiment

Autor: Coombs, George Rufus

This thesis presents a new absolute luminosity calibration measurement at the LHCb experiment for pp collsions at √s = 13 TeV measured via the beam-gas imaging (BGI) technique with data acquired in the 2016 luminosity calibration session. The measu

The LHCb Vertex Locator (VELO) is used to reconstruct beam–gas interaction vertices which allows one to obtain precise profiles of the LHC beams. In LHCb, this information is combined with the profile of the reconstructed beam–beam collisions and

The high design luminosity of the SuperKEKB electron-positron collider is expected to result in challenging levels of beam-induced backgrounds in the interaction region. Properly simulating and mitigating these backgrounds is critical to the success

At future linear and circular colliders, beam halo can strongly limit machine performances, cause as well component damage and activation, and should, therefore, be controlled by an efficient collimation system. To evaluate the impact on particle phy
