Trapped Atom Clock on a Chip - TACC — Clement Lacroute1, Friedemann Reinhard2, Christian Deutsch2, Fernando Ramirez-Martinez1, Jakob Reichel2, and •Peter Rosenbusch1 — 1SYRTE, Observatoire de Paris, FRANCE — 2LKB, Ecole Normale Superieure, Paris, FRANCE
We present a new project of a microwave clock interogating magnetically trapped atoms using the atom chip technology. The project builds on the demonstration experiment [P. Treutlein et al., Phys. Rev. Lett., vol. 92, 203005 (2004)] but aims at an improved stability of a few 10−13 at 1 s while remaining of breadboard size. TACC will be able to operate with magnetically trapped thermal atoms or a Bose-Einstein condensate, thereby being one of the first experiments to use condensates in a metrological apparatus. We present the current status of the experiment.
