Overview of ATLAS forward proton detectors for LHC Run 3 and plans for the HL-LHC
November 01, 2022
A key focus of the physics program at the LHC is the study of proton-proton collisions after the interaction. An important class of processes that can be studied are the ones where protons remain intact. In such cases the electromagnetic fields surrounding the protons can interact producing high energy photon-photon collisions. Alternatively, interactions mediated by the strong force can also result in intact forward scattered protons, providing probes of quantum chromodynamics (QCD). In order to aid an identification and provide a unique information about these interactions, instrumentation to detect and measure protons scattered through the very small angles is installed in the beam-pipe far downstream on both sides of the interaction point. In this paper, the description of the ATLAS Roman Pot Detectors (AFP and ALFA), their performance
to date and expectations for the upcoming LHC Run 3 is discussed. The physics of interest, beam optics and detector options for the extension of the programme into the High-Luminosity LHC (HL-LHC) era are also discussed.
