Open Day, Monday,
3 October 2022, 9 - 18 Uhr


On Monday, 3.10.2022, we will guide you through one of the world’s most modern research neutron sources.

Look at the reactor pool and learn more about the non-destructive investigation of matter with neutrons. There is plenty of information, lectures, films, games, Lego models of scientific instruments and the opportunity to have your own questions answered by our scientists:

  • Who is working on the research neutron source FRM II??
  • How does such a high-performance research reactor work?
  • What is radioactivity and where do we encounter it in everyday life?
  • Why are neutrons used for research?
  • Why are radioisotopes/radiopharmaceuticals used for cancer therapy?
  • Why can bacteria become resistant to antibiotics?



Then visit the Heinz Maier-Leibnitz Zentrum at the research neutron source Heinz Maier-Leibnitz (FRM II) on Monday, 3.10.2022.
The meeting place this time is the new Science Congress Center Munich (GALILEO), Walther-von-Dyck-Strasse 10, 85748 Garching near Munich.


For guided tours please register in advance:

On the open day there will be guided tours through the research neutron source again. All visitors have to register and it means to be fast and not to come without a valid identity card!

You can already register for 03 October under the following link:


Very important: Please note our access rules:

  • Minimum age: 18 years,
  • valid identity card or passport, non-EU citizens need a valid passport (residence permits or driving licenses are not accepted),
  • no access for pregnant women and nursing mothers,
  • no cameras or cell phones allowed (personal items can be left free of charge at our checkroom),
  • long pants (covered legs) as well as closed shoes are obligatory (visitors' path leads over gratings for longer distances),
  • no barrier-free access.

Meeting place & checkroom
Science Congress Center Munich (GALILEO), Walther-von-Dyck-Straße 10, 85748 Garching

Information booth of the FRM II and MLZ with:

  • Lego model of scientific instruments (TRISP, ANTARES)
  • Short films
  • Neutron game for children
  • Information material on the research neutron source
  • Information material on the world's most intensive positron source "NEPOMUC"

Information booth of the Radiation Protection with:

  • Tasks of radiation protection at the research neutron source
  • Measuring instruments for the determination of radioactivity
  • Exhibits for self-measurement
  • Environmental monitoring of the FRM II: What is tested for radioactivity how and where?

Information booth of the Positron Source with:
The Physics Department operates the world's most intense positron source at FRM II.

    How are these exotic particles generated?
    What are the current research areas in positrons?

The short films give an insight into the research, medical and industrial applications at FRM II and the functioning of the research neutron source.
