We are interested in cooling process both of internal degrees of freedom, as well as external (kinetic) degrees of freedom. 

The Cryogenic Storage Ring (Heidelberg)

The Cryogenics Storage Ring (CSR) is a fully electrostatic heavy ion storage ring operating at very low (few Kelvins) temperature. The CSR, located at the Max-Planck Institute for nuclear Physics in Heidelberg is a unique instrument dedicated to the study of cold molecular and cluster ions. 

The Electrostatic Ion Beam Trap

The Electrostatic Ion Beam Trapping

An ion trap usually stores an ensemble of ions as a cloud, using time dependent electromagnetic fields. We have developed a new type of ion trap, which is able to store an ion beam.
