Vacuum System

The sketch of a top view on our vacuum system shows its main components:
 

Outline of the vacuum system.

Two glass cells in two regions of vacuum are separated via a differential pumping stage. We collect Rubidium and Potassium atoms in the bigger glass cell on the left. Then we transport our atoms mechanically with moving magnetic coils to region with a much better vacuum, where we cool the atoms down to a few hundred Nanokelvin above absolute zero in a magnetic trap.  

The two pictures show the MOT-cell on the left and the science cell on the right. Our setup allows us a very good optical access for further experiments on quantum degenerate gas mixtures. In the picture above, the harmonic magnetic trap was not installed. Here is a picture of the magnetic trap, three coils in the so called QUIC configuration:
