Our goal is to establish a pilot facility - at the FAIR heavy-ion synchrotron SIS100 - for laser cooling of bunched relativistic heavy-ion beams. Beams of highly charged ions will first be produced by the GSI Helmholtz centre for heavy ions in Darmstadt, Germany, and will then be injected into the FAIR SIS100 where they will be stored, bunched, and accelerated to highly relativistic energies. With the aid of the pilot facility, these ions beams will finally be laser-cooled and transformed into very cold and very short relativistic heavy-ions bunches for experiments.
This activity is part of subtopic 2 from Accelerator Research & Development (ARD), of the „Matter and Technologies“ program within POF III and POF IV of the Helmholtz association.
Our activities are concentrated on the technical development of laser and detection systems (BMBF funded), the design and construction of the laser beamline and the laboratory at the SIS100, and on (the optimisation of) measuring methods and controls for laser cooling. In the following, an overview is given of the concrete projects of the different groups and their research activities in this field.
