MAGIS-100: Fundamental Science with Atom Interferometry

POSTER

Abstract

MAGIS-100 is an atom interferometric sensor over a vertical baseline of 100 m currently under construction at Fermilab. By implementing clock atom interferometers at either end of this baseline, MAGIS-100 will be sensitive to potential signatures of ultralight dark matter with scalar and vector couplings. Additionally, by measuring the light travel time along the baseline, MAGIS-100 will serve as a pathfinder for a gravitational wave observatory in the mid-band, with frequencies from 0.1-1 Hz. With free-fall times up to nine seconds, MAGIS-100 will test quantum superposition at macroscopic scales of length (meters) and time (seconds). We present the science goals of the MAGIS-100 instrument and designs for its vacuum, magnetic, and laser systems.

*The MAGIS project is an collaboration between Stanford University, Fermilab, and six other universities in the United States and the United Kingdom. The MAGIS collaboration is funded by the Gordon and Betty Moore Foundation under grant no. GBMF7945 as well as the Department of Energy’s QuantiSED initiative 2019.
