We propose a new scheme to test the second equivalence principle using guided atom interferometer.The second equivalence principle states that the ratio of inertia mass to gravitational mass of a body is a constant independent of its angular momentum.The matter wave guide is formed by a diffraction-free Bessel laser beam whose cross-section is a circular ring.Thus, in blue detuned situation, a circular ring trap is formed in the transverse plane.If the laser beam propagations along the gravity direction, atoms would fall down freely in the vertical direction.After cold atoms loading into the matter wave guide, we use Raman-Nath diffraction laser pulse to coherently split the atom wave to the opposite directions in the transverse plane of the wave guide.Consequently, the two partial matter waves have opposite angular momenta, respectively.After periodic rotation, we use another Raman-Nath diffraction laser pulse to recombine the two partially coherently matter waves.And then interference fringes occur.Based on the interference signal, the E(o)tv(o)s parameter can be obtained.Our theoretical analysis shows that the E(o)tv(o)s parameter is inversely proportional to the square of the acceleration of gravity, and also inversely proportional to the cube of the interrogation time.In the ground based experimental situation, the measurement sensitivity of the E(o)tv(o)s parameter of 10-8 might be achieved.In the microgravity and typical experimental parameters conditions, the measurement sensitivity of 10-13 is estimated by our theoretical model.After further optimization of the experiment, we wish the proposal can be used in the experimental study of the quantum gravity.
