New physics has traditionally been expected in the high-pT region at high-energy collider experiments. If new particles are light and weakly-coupled, however, this focus may be completely misguided: light particles are typically highly concentrated within a few mrad of the beam line, allowing sensitive searches with small detectors, and even extremely weakly-coupled particles may be produced in large numbers there. We have propose a new experiment, ForwArd Search ExpeRiment, or FASER, which will be placed downstream of the ATLAS interaction point in the unused service tunnel TI12 and operated concurrently there. FASER will complement the LHC's existing physics program and extend its discovery potential to a host of new particles, such as dark photons and axion-like particles. In this talk, I will describe FASER's location and discovery potential, the detector's layout and components, as well as the experiment's timeline.
