Daniel Bemmerer

Daniel Bemmerer serves as Professor and Group Leader of Nuclear Astrophysics at Helmholtz-Zentrum Dresden-Rossendorf (HZDR), where he also holds the position of Technical Director for the Felsenkeller accelerator facility. His work focuses on experimental measurements of nuclear reactions critical for understanding stellar evolution and nucleosynthesis, utilizing low-background underground environments to achieve high-precision data essential for astrophysical models.

His research centers on low-energy nuclear reaction cross sections relevant to stellar burning processes, including the CNO cycle, neon-sodium cycle, and carbon fusion. He specializes in developing advanced experimental setups—such as gas target systems and neutron detectors—for studying reactions involving isotopes of hydrogen, helium, carbon, neon, and oxygen at energies corresponding to stellar interiors. His methodologies address key challenges in background suppression and energy resolution for underground nuclear astrophysics.

Analysis of his recent publications (2023-2025) reveals a consistent emphasis on direct measurements of astrophysically critical reactions, particularly 12C+12C, 22Ne(p,γ)23Na, and 17O(p,γ)18F. These studies leverage underground facilities like Felsenkeller and LUNA to minimize cosmic-ray interference, providing refined reaction rates that impact models of solar neutrino fluxes, classical novae, and massive star evolution. His work increasingly integrates advanced data analysis techniques like R-matrix fitting to reduce uncertainties in stellar reaction networks.

While specific details of student supervision and grant funding were not disclosed, his leadership of the Nuclear Astrophysics group at HZDR implies active mentorship of doctoral researchers and participation in collaborative international projects. His role as Technical Director of the Felsenkeller accelerator suggests involvement in securing infrastructure funding for nuclear astrophysics experiments.

Professor Bemmerer directs operations at the Felsenkeller shallow-underground laboratory, which houses a 5 MV Pelletron accelerator at 47 meter water equivalent depth in Dresden. This facility enables precision measurements of low-energy nuclear reactions through specialized setups including jet gas targets and neutron detectors. His team maintains strong collaborations with the LUNA collaboration at Gran Sasso, Italy, and contributes to global efforts in understanding stellar nucleosynthesis through underground nuclear physics.
