Abstract

The ATLAS Forward Proton (AFP) detector system aims at the measurement of protons scattered diffractively or electromagnetically at very small angles. The first arm of the system was installed in 2016 and AFP took data in several commissioning and physics runs. The installation of the second arm is ongoing and will be completed in time for the 2017 data taking period. This will allow the measurements of processes with two tagged forward protons being a signature of: central diffraction, exclusive production, and two-photon processes. The early results and experience from the first year of data taking is presented together with the status of the second-arm installation and plans for the future.
