University of Mainz

With more than 35,000 students Johannes Gutenberg-Universität at Mainz is one of the ten largest universities in Germany. In the fields of natural science the Cluster of Excellence on "Precision Physics, Fundamental Interactions and Structure of Matter" (PRISMA), and the Graduate School of Excellence "MAterials Science IN MainZ" (MAINZ) are considered among the elite research groups worldwide while unique large-scale research equipment includes the TRIGA light water research reactor and the MAMI electron accelerator devoted to hadron physics.

In relation to LA³NET activity, researchers from the Institute of Physics of Mainz University have contributed pioneering work for production and spectroscopy of exotic nuclides at the world leading on-line facilities using laser systems. These activities date back to early pulse laser applications in gas cells in the 1960s, the first demonstration of high resolution techniques like collinear laser spectroscopy on radioisotopes in the 1970s, still active up to now, and range up to the implementation of dedicated high repetition rate all solid state laser systems for resonant ionization laser ion sources and in-source spectroscopy. Nowadays these have been installed at ISOLDE, CERN, Switzerland; ISAC, TRIUMF, Canada; JYFL, Jyväskylä, Finland; GISELE, GANIL, France and PALIS, RIKEN, Japan and ISOL, RISP, Korea; while further collaborations  extend to the US, Belgium and Russia.

Today the working group Quantum/LARISSA headed by Prof. Klaus Wendt contributes these development of lasers and techniques to the aforementioned applications in atomic and nuclear structure research and in on-line ion source optimization. In addition similar laser based techniques are applied at Mainz for highly selective ultra trace determination of radioisotopes in close collaboration with the Institute of Nuclear Chemistry and the TRIGA research reactor facility.
