News: First results from CSR published in PRL (March 2016)


Results from the first cryogenic phase of the CSR were published in PRL. We studied the near-threshold photodissociation of CH+ inside the storage ring. In combination with state-of-the-art theoretical calculations we were able to assign all resonances of the photodissociation spectra for J=0-2 and monitor the slow rotational decay inside the CSR for up to 240s. After about 1 minute of storage time, only the two lowest rotational states hold significant population fractions.

Laboratory Astrophysics 2015 / Workshop at MPIK


We hosted the 2015 meeting on Laboratory Astrophysics on Oct 1-2 2015 at MPIK. The meeting brings together the German groups working in the field plus selected international guests.  The workshop website can be found here:

Elisabeth Guerin joins our group!


Elisabeth will be joining us as a master student. She will be working on the neutral beamline at the CSR.
Welcome!

NEWS: We welcome Dr. Sunil Kumar!


Dr. Sunil Kumar has started a PostDoc position in our group on November 1st. He will be working on the Spectroscopy of complex organic molecules in a cryogenic ion trap. Welcome!

News: First beam stored in the CSR!


On March 17th 2014 the first ion beam was successfully stored in the Cryogenic Storage Ring (CSR).

Although the CSR has not been cooled yet to liquid helium temperature, this milestone constitutes a huge success,
as the storage ring optics and the detectors are all connected and functioning as foreseen.

Congratulations to Robert von Hahn, Manfred Grieser, Andreas Wolf, and the entire CSR team,
including the technical units and the workshops!

News: Our Coulomb Explosion results with Chiral Molecules were published in SCIENCE


In collaboration with the group of Prof. Oliver Trapp (Heidelberg University),
we have taken the first snapshots of enantio-selected chiral molecules in the gas phase.
