Abstract

We have developed a dual-rubidium-isotope magneto-optical tap (MOT) for a dual species co-magnetometer used in measurements of the electron electric dipole moment (EDM) using laser-cooled francium atoms. The EDM measurement using atoms in an optical dipole force trap exhibits the advantage of less Doppler effects and longer interaction time compared to atomic and molecular beam experiments. In EDM experiments, the fluctuation of the magnetic field and the vector light shift induced by an optical dipole force can cause systematic errors. The dual species co-magnetometer is being developed to simultaneously monitor the fluctuations of both the magnetic field and the vector light shift. We demonstrated the dual-rubidium-isotope MOT for the development of the dual species co-magnetometer.
