This is in particular true for the observation of extreme distance, time, and energy scales investigated within the scope of the Helmholtz research sector “Matter”. That is why real “sci fi tools” are needed to trace the hidden properties of matter surrounding us: Detectors. Detectors are the “eyes” which permit scientists to monitor new effects, penetrate into new realms, and, thus, gain new and sometimes groundbreaking insights.

Highly sensitive detectors are capable of, for example, detecting and counting charged particles, neutrons, and photons (e.g. visible light, infrared radiation, or X-rays). One such detector is the Geiger-Müller counter which can detect radiation from radioactive decays. The use of detectors is, thus, not limited to fundamental research or research on the structure of matter. In fact, detectors are also employed in industry and medicine and moreover in a broad range of commercial applications.

The great variety of applications ranges from detectors for experiments on fundamental nuclear and astrophysical research at the accelerator facility of the GSI Helmholtzzentrum für Schwerionenforschung (Helmholtz Center for Heavy Ion Research) and ist Facility for Antiproton and Ion Research FAIR to applied fundamental research on nuclear transmutation and materials research with positrons at the HZDR’s electron accelerator ELBE all the way to detectors used in radiooncology in order to further increase the precision of tumor therapy using charged-particle radiation.

The HZDR participates in the Helmholtz portfolio process on the topic Detector Technologies and Systems.


Objectives

  • Establishing cooperation across the Helmholtz Association for the development of new detectors and detector concepts
  • Usage and supply of HZDR infrastructure and know-how (detector laboratory, knowledge in detector construction, accelerator facilities) for the development and characterization of novel detectors
  • Applications of new detectors and detector concepts in medical applications (in collaboration with the National Center for Radiation Research in Oncology ‒ OncoRay) and technological applications (e.g. analysis of materials using positron-annihilation-energy and lifetime spectroscopy)
