  In this paper we demonstrate a magnetically guided Cesium (Cs) atom
interferometer in the Talbot-Lau regime for inertial sensing with two
interferometer schemes, Mach-Zenhder and Ramsey-Borde. The recoil frequency of
the Cs atoms and the acceleration along the waveguide symmetry axis is
measured. An acceleration measurement uncertainty of $7\times10^{-5}$ m/s$^{2}$
is achieved. We also realize an enclosed area of $0.018$ mm$^{2}$ for rotation
measurement. As the first reported magnetically guided Cs atom interferometer,
the system limitation and its advantages are discussed.
