Dr. Fabian Kuger

I'm a PostDoc working on the DARWIN project and associated detector R&D on liquid xenon Time Projection Chambers. As in my past work for the ATLAS NSW project, I am dedicated to the optimization of detector technology, based on the combination of experimentally obtained results and detailed simulation studies and model development.

Current research topics: 

  • The science portfolio of a future multiple-ton liquid xenon TPC, like the DARWIN observatory, includes a plethora of science cases beyond the detector's primary objective: the direct detection of WIMP dark matter.
    • As a leader of the DARWIN working group on 'simulation and sensitivity,' I focussed on the detailed background assessment. This is used to derive design constraints, radiopurity requirements, and detector performance benchmarks, which are mandatory to reach DARWINs 'ultimate' WIMP sensitivity, limited by the irreducible neutrino background.
    • I lead the effort to investigate the competitiveness of DARWIN in the search for 0vbb of 136Xe compared to dedicated proposed 0vbb experiments, such as EXO, NEXT-HD.
    • A study on a novel multiple-interaction site analysis scheme for tagging of the hypothetical resonant 0vECEC decay of 124Xe, relying on a highly efficient cluster-combinatorics approach,  is currently ongoing.
  • Within the 2021 formed consortium between LZ, XENON and DARWIN, I am involved in the assessment of the scientific reach of a jointly proposed future liquid xenon detector for dark matter searches and astrophysical studies.
  • The optimization of the liquid xenon TPC technology is key for a successful next-generation experiment, be it DARWIN or a joint LZ-X-D endeavor. Using the Freiburg XeBRA detector platform, I and my team investigate two design approaches:
    • a hermetically (semi)-sealed TPC design for reduction of the xenon intrinsic 222Rn background.
    • the single-phase with amplification in liquid (spell) technology as an alternative charge-to-light-conversion mechanism which has the potential to lift some of the most daunting design constraints for large diameter TPCs.
