Progress towards a permanent electron electric dipole moment search using cold atoms in an optical lattice

Observation of a permanent electric dipole moment of the electron would imply CP violating effects not contained in the Standard Model. We present our progress towards measuring the electron EDM using laser-cooled cesium and rubidium atoms trapped in a one dimensional optical lattice. We have launched laser-cooled Cs atoms in a cavity-enhanced optical lattice guide. We re-cool and re-trap the atoms in the 90 cm high measurement region, obtaining an overall transfer efficiency from the magneto-optic trap of 50\%. We will describe the development of two such lattices in parallel, passing between specially-coated fused silica electric field plates.
