Dark Matter group in IKP-KIT
The Dark Matter group at Karlsruhe Institute of Technology (KIT) searches for weakly interacting massive particles (WIMPs) as possible candidates for "dark matter", one of the greatest mysteries of the universe. The EDELWEISS collaboration consists of 11 institutes from 4 countries. The experimental setup is based on array of Germanium bolometers installed in the Frejus road tunnel in the underground laboratory (Laboratoire Souterrain de Modane, LSM), which shields the experiment by 1800m of rock (4850 m.w.e.). The bolometer detectors can detect WIMPs via their elastic scattering off Germanium nuclei and have an excellent background rejection power. In the research group at the Institute for Nuclear Physics (IKP), the muon veto system was designed, built and is being operated. Besides the analysis of experimental data, we also provided a new electronic data read-out in cooperation with our partner institute IPE at KIT. The EDELWEISS experiment is now in its third stage, EDELWEISS-III, concentrating on the search of so-called low mass WIMPs with maases in the GeV range.
We also perform a research and development (R&D) programme for the running experiment as well as for next stage Dark Matter experiments, e.g. potentially combining Ge and Si bolometers with the SuperCDMS experiment at SNOLAB in Canada (as part of the EURECA study), or the search for light Dark Matter in the MeV mass range with DELight.
