Abstract	FASER is a new experiment designed to search for new light weakly-interacting long-lived particles (LLPs) and studying high energy neutrinos in the very forward region of the LHC collisions at CERN. The experimental apparatus is situated 480 m downstream of the ATLAS interaction-point aligned with the beam collision axis. The FASER detector includes four identical tracker stations constructed from silicon micro-strip detectors. Three of the tracker stations form a tracking spectrometer, and enable FASER to detect the decay products of LLPs decaying inside the apparatus, whereas the fourth station is used for the neutrino analysis. All tracker stations have been installed in the LHC complex in 2021. FASER has already started physics data taking since the LHC resumed operation in July 2022. This contribution describes the design, construction and early data of the tracker stations.
