Emmy Noether-Group "Direct Dark Matter Searches"
Dr. Belina von Krosigk
My group currenlty focuses on two main research projects:
- Direct searches for LDM (Light Dark Matter), ALPs (Axion-Like Particles), and dark photons with SuperCDMS detectors
- Optimization of FPGA-based trigger algorithms
Both topics go hand-in-hand as a lower trigger threshold implies sensitivity to lower masses of the aforementioned dark matter candidates.
The local research is part of the international SuperCDMS experiment, which is an experiment optimized for direct WIMP (Weakly Interacting Massive Particles) searches and is additionally highly sensitive to other dark matter candidates like LDM, ALPs and dark photons. The experiment makes use of cryogenic silicon and germanium detectors and is currently being built at SNOLAB, a 2 km deep underground laboratory in Canada. Data taking is expected to start in 2021.
Our local research projects are a significant contribution to the SuperCDMS physics program and to the enhancement of the low mass sensitivity of SuperCDMS detectors. Our research on FPGA trigger algorithm optimization additionally allows for collaborations with other research groups both within and outside of the physics community.
In May 2020 we also joined the international DARWIN collaboration and we are starting our associated research activities over the course of this year. DARWIN is an upcoming experiment which is also being optimized for direct WIMP searches. The goal of the collaboration is to build the ultimate dark matter detector, using a multi-ton liquid xenon time projection chamber.
This group is supported by and part of the Cluster of Excellence Quantum Universe.
The research is funded by the Emmy Noether Programme of the "Deutsche Forschungsgemeinschaft" (DFG).
