Atom cooling in a ring — •Andreas Ruschhaupt — Institut fuer Mathematische Physik, TU Braunschweig, Mendelssohnstr. 3, D-38106 Braunschweig

We propose a method to cool atoms in a ring. An atom diode -a laser device which can by passed by atoms in only one direction- is put in a ring in such a way that the velocity of the crossing atom is also decreased. In addition, the atom is trapped if its velocity is below a threshold velocity. In this manner, the atom or an atom cloud moving in the ring can be cooled and finally trapped after repeated passages of the atom diode.
