The section Subatomic Physics focuses on the following reasearch areas:
- astroparticle physics (AG Jochum)
- hadron nucleus interactions (AG Clement)
- nuclear matter under extreme conditions (AG Schmidt)
- neutrino physics (AG Lachenmaier)
An underground laboratory was constructed in the years 2005-2006 next to the physics building. It is designed to conduct tests of cryogenic detectors with a reduced cosmic ray flux.
Until 2018, the section operated a 3MV Van de Graaff accelerator at the Rosenau for research and education purposes. It was regularly used for courses in radiation protection and a nuclear physics lab course was offered for students.
The possibility to create neutrons in a wide energy range between a few keV and 20 MeV made the facility interesting for questions in astro particle physics research, e.g. for testing novel detector concepts. At the moment the facility is being decomissioned.
