Description
A key focus of the physics program at the LHC is the study of head-on proton-proton collisions. However, an important class of physics can be studied where the protons narrowly miss one another and 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. Instrumentation to detect and measure protons scattered through very small angles is installed. We describe the ATLAS Forward Proton Detectors (AFP and ALFA), including their performance to date, covering Tracking and Time-of-Flight Detectors as well as the associated electronics, trigger, readout, detector control and data quality monitoring. The physics interest, beam optics and detector options for the extension of the programme into the HL-LHC are also discussed. Finally, a glimpse on the newest results will be given.
