• KM3NeT – a future km³-scale neutrino telescope in the Mediterranean Sea
  

  To fully exploit the scientific potential of neutrino astronomy, neutrino telescopes of cubic-kilometre scale will be required. The first such detector (IceCube) is currently under construction at the South Pole. In order to achieve full sky coverage and to be able to observe the Galactic Centre, a complementary detector of this size – KM3NeT – shall be built in the Mediterranean Sea.The European deep-sea neutrino projects, ANTARES, NEMO and NESTOR, are jointly working towards the implementation of the KM3NeT detector. A 3-year FP6 Design Study running since 2006 aims at producing the Technical Design Report for the KM3NeT detector. The remaining legal, governance, organisational and funding issues are to be addressed in a 3-year FP7-funded Preparatory Phase project that started in 2008. If all open questions are settled in due time, KM3NeT construction could thus commence in 2011.KM3NeT will also provide the infrastructure for research projects of other science communities, such as biologists, environmental scientists, geologists/geophysicists and oceanographers.KM3NeT is included in the 2006 and 2008 Roadmaps of the European Strategy Forum on Research Infrastructures (ESFRI).Since Oct. 2003: European coordinator of the KM3NeT Design Study, spokesperson of the KM3NeT consortium. Since 2008: coordinator of the two work packages Data and Control and User Support and Impact Assessment of the KM3NeT Preparatory Phase.

• ANTARES – cosmic neutrinos in the Mediterranean Sea
  

  The ANTARES experiment is fully operational since May 2008. It is constructed to detect high-energy cosmic and atmospheric neutrinos by measuring the Cerenkov light emitted in the water of the Mediterranean Sea by the charged leptons (electrons, muons) produced in charged-current reactions of the neutrinos. The detector consists of a large volume of sea water in about 2 kilometres depth off the shore of Toulon, instrumented with photomultipliers optimised for detecting upward-going neutrinos. The physics goals of this experiment, and of the even larger next-generation successor project, are amongst others:

  • Search for point sources of cosmic neutrinos and for diffuse neutrino flux from the universe;
  • Measurement of the energy spectrum of neutrinos in the range from a few 10 GeV to about 1 PeV;
  • Search for the annihilation of WIMPs (e.g. neutralinos) which may be gravitationally trapped in the centre of our galaxy, in the sun or in the earth;
  • Search for exotic phenomena, such as magnetic monopoles or nuclearites.

  Member of the ANTARES Collaboration since November 2001. Contributions to the ANTARES detector; participation in the ANTARES simulation, reconstruction and data analysis work; contributions to the detector integration (LED beacons, clock cards, acoustic detection test system).

  2002-2005 responsible for the coordination of the R&D work towards a future cubic kilometre detector in ANTARES and member of the ANTARES Steering Committee.

• AMADEUS – towards acoustic detection of neutrinos
  

  One major contribution of the Erlangen group to ANTARES was the development of the AMADEUS system for testing the feasibility of a future large-scale detector for acoustic detection of neutrinos with energies in the EeV range and above. AMADEUS stands for “Antares Modules for Acoustic Detection under the Sea”; the system comprises 36 hydrophones including their readout chain. Data are continuously digitised and sent to shore, where they are processed by an online filter.

  • Design, construction, testing and operation of the AMADEUS system was and is done mainly in Erlangen.
  • Data analysis is in progress. The first results confirm that the system works according to specifications.

• H.E.S.S. – a Cherenkov telescope for TeV gamma rays
  

  H.E.S.S. (for High-Energy Stereoscopic System) consists of four telescopes in the Khomas plateau in Namibia, each with a total mirror area of 108 square metres. These telescopes record the Cherenkov light produced by the electromagnetic cascades that evolve when a high-energy photon enters the atmosphere. The stereoscopic observation mode allows for a precise direction reconstruction. The typical energy range is between a few 100 GeV and about 100 TeV.Many exciting observations and discoveries were made with H.E.S.S. In 2007, the collaboration was awarded the European Descartes prize.Currently, a fifth telescope is under construction, centred between the first four ones and much larger than these. With this telescope, the sensitivity of H.E.S.S., in particular at the lower end of the energy spectrum, will be significantly increased.The H.E.S.S. and MAGIC collaborations aim at constructing a much larger array of Cherenkov telescopes, the Cherenkov Telescope Array (CTA). This project is included in the 2008 Roadmap of the European Strategy Forum on Research Infrastructures (ESFRI).Member of the H.E.S.S. collaboration since 2006.

    Simplified simulation and reconstruction software to support decisions in design phase. Contributions to proposal and project planning.Sept. 1999 – March 2001: coordinator of the MVD-Offline activities.

• THERA – a TESLA+HERA option
  

  In the framework of the TESLA TDR we studied the option to collide electrons from TESLA with protons from HERA to produce ep reactions with a centre-of-mass energy of about 1 TeV. These studies have been summarised in an Appendix to the TESLA TDR and resulted in a detailed investigation of the the physics potential of ep collisions at this energy, the THERA Book.Co-Convenor of the detector group of the THERA study.Co-Editor for the THERA contribution to the the TESLA Technical Design Report (Jan./Feb. 2001) and for the THERA Book (DESY-LC-REV-2001-062, Dec. 2001).
