  We describe the main components of the ATLAS Forward Physics project, namely
the movable beam pipe, the tracking and timing detectors which allow to detect
intact protons in the final state at the LHC. The position detector is composed
on 6 layers of 3D silicon detectors readout by FE-I4 chips developped for
ATLAS. The fast timing detector is built from a quartz-based Cerenkov detector
coupled to a microchannel plate photomultiplier tube, followed by the
electronic elements that amplify, measure, and record the time of the event
along with a stabilized reference clock signal, ensuring a time resolution of
10-15 picoseconds.
