Phase-0 Experiments using the R3B CALIFA Demonstrator — •Lukas Ponnath for the R3B collaboration — TU München, Deutschland

Studies on the rapid neutron capture process (r-process) nucleosynthesis try to clarify the origin of the heaviest elements in the universe, which was once titled as "one of the 11 greatest unanswered questions of mondern physics". A deep insight and understanding of the structure of exotic (neutron rich) nuclei is mandatory in order to model the r-process under different astrophysical conditions.

The upcoming R3B (Reactions with Relativistic Radioactive Ion Beams) experiment at the research facility FAIR, currently under construction in Darmstadt, will enable a kinematic complete measurements to gain a deep insight to the nuclear structure far from stability.

One of the key instruments of the R3B experimental setup will be the highly segmented CALIFA calorimeter surrounding the R3B reaction target. For in flight detection of gamma-rays and light charged particles this will provide unique resolution for relativistic beam energies.

We will present first results of the Phase-0 experiments of R3B scheduled for February 2019 with the CALIFA demonstrator combined R3B detectors and the GLAD magnet for the first time.
