Title: Status of the AFP project in the ATLAS experiment

Status of the AFP project in the ATLAS experiment is summarized. The AFP system is composed of a tracker to detect intact, diffractively scattered protons, and of a time-of-flight detector serving to suppress background from pile-up interactions. The whole system, located around 210 m from the main ATLAS detector, is placed in Roman Pots which move detectors from and to the incident proton beams. A typical distance of the closest approach of the tracker to these beams is 2–3 mm. The main physics motivation lies in measuring diffractive processes in runs with not a very high amount of pile-up.
