COLLAPS

Laser Spectroscopy at ISOLDE/CERN

ISOLDE is an isotope production facility at Europe’s largest accelerator laboratory CERN. It is one of the world’s leading facilities in producing short-lived isotopes at low energies as they are required for collinear laser spectroscopy The COLLAPS setup, installed in the experimental hall at ISOLDE, is the “senior” and forerunner of all collinear laser spectroscopy experiments and, nevertheless, still one of the most productive’s of its kind. During a long shutdown of CERN, the laser laboratory has been completely renewed. Operation has restarted after the last shutdown in 2021 with successful runs on tellurium and lead. Project currently concentrate on the Sn and Pb region. Another project (ROC) aims at measuring the charge radii of calcium-53,54. Stay tuned to learn about these results ….

The COLLAPS setup, orginally initiated and built by the Johannes Gutenberg-University Mainz, is currently supported by the MPIK Heidelberg, the TU Darmstadt and the KU Leuven. Further collaboration partners are amongst others colleagues from the Liverpool University, the MIT and Beijing University.

The local team at CERN currently consists of Dr. Liss Vasquez Rodriguez, Dr. Peter Plattner, Dr. Mark Bissel und M.Sc. Tim Lellinger.
