Conclusions

  • Astroparticle physics is a very lively and growing field in Germany
  • Strong scientific and methodic links to particle and nuclear physics,

particularly to non-accelerator particle physics

  • German groups are in (co-)leading roles in all major topics of astroparticle physics
  • More diverse field than particle physics,

not located around one huge facility like CERN → some problems in funding

  • Community building: Helmholtz Alliance for Astroparticle Physics HAP
  • Future projects (see also talk by S. Schönert):
  • cosmic rays: Auger upgrade
  • high energy gamma rays: CTA (major German APP project in the future)
  • ultra-high energy neutrinos: PINGU? (mass hierarchy), DecaCube?, KM3NeT?
  • dark matter: XENON1T, EURECA (with SuperCDMS?)
  • neutrino properties: GERDA phase II, KATRIN (both funded, starting soon)
  • Funding:

federal ministery BMBF (Verbundforschung: 18 MEuro for 2011-2014, 2014-2017?), Helmholtz Association, Max Planck Society MPG, German Science Foundation DFG, various universities (state budget)
