Title: MAGIS-100: Large Baseline Atom Interferometery

Abstract:
As large baseline atom interferometers are being constructed and planned, such as MAGIS -100 (Matter-wave Atomic Gradiometer Interferometric Sensor) and AION (Atom Interferometry Observatory Network), considerations of the experimental systematics and their mitigation are important for guiding design and development of the detectors to ensure optimal measurement sensitivity. The transition from tightly controlled lab spaces to mining shafts, as well as extending the baseline length, alter leading order systematics. For example: Coriolis accelerations, laser wavefront perturbations, and crucially for terrestrial detectors, gravity gradient noise. Current analysis and future outlook for these effects and the state of MAGIS will be presented.
