On 3.10.2024, 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?
CURIOUS?
Then visit the Heinz Maier-Leibnitz Zentrum at the research neutron source Heinz Maier-Leibnitz (FRM II) on Tuesday, 3.10.2024. The meeting place this time is
Physics Building of the Technical University of Munich, James-Franck-Str. 1, 85748 Garching
For guided tours please register in advance at https://indico.frm2.tum.de/event/508/
How to register for the tours?
The Heinz Maier-Leibnitz Zentrum and the Research Neutron Source Heinz Maier-Leibnitz (FRM II) will be offering guided tours on Thursday, October 3, 2024, in addition to information stands. There will be two guided tours in English language in the morning and another two in the afternoon.
The meeting point is in the Physics Building of the Technical University of Munich, James-Franck-Str. 1, 85748 Garching near Munich.
NOTE: Unfortunately, all places on our guided tours are fully booked for this year. We are very pleased about the great interest and hope to welcome you at a future event. However, you are welcome to visit us at our information stands in the foyer of the TUM Department of Physics on 3 October 2024!
Please also take a look at our website to find out more about our research work and not to miss upcoming events. Thank you for your understanding!

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!
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 as well as closed shoes are obligatory (visitors' path leads over gratings for longer distances),
- Unfortunately we can not provide completely barrier-free access at our Open day.

In addition to information stands and guided tours, the Heinz Maier-Leibnitz Zentrum and the Research Neutron Source Heinz Maier-Leibnitz (FRM II) will also be offering two lectures on Thursday, 3 October 2024 on the premises of the TUM School of Engineering and Design.
PLEASE NOTE: The location of the lectures is NOT the TUM Department of Physics. You will only find our information stands in the foyer of the TUM Department of Physics. Our lectures will again take place at the TUM School of Engineering and Design.

10:15 a.m. - Talk: Eiskalt durchleuchtet - Wie die Bildgebung mit Neutronen ungeahnte Einblicke in unterschiedlichste Objekte ermöglicht
Neutronen bieten atemberaubende Einblicke in das Unsichtbare: Schon einmal darüber nachgedacht, wie die Erdbeeren
für das Müsli gefriergetrocknet werden? Wie verhindert man, dass die Nadeln von Fertigspritzen verstopfen und so Medikamente nicht richtig injiziert werden? Oder: Wie haben Dinosaurier gebrütet? Erfahrt, wie Neutronen unsere Welt revolutionieren – und was sie in Zukunft noch alles möglich machen könnten. Seid dabei und entdeckt die Geheimnisse hinter Neutronen in diesem Vortrag!
Dr. Michael Schulz, Forschungs-Neutronenquelle Heinz Maier-Leibnitz (FRM II)
2:15 pm - Talk: Klein aber H2O – warum brauchen wir Wasser zum Leben?
Wasser ist mehr als nur ein Lebenselixier – es ist der Schlüssel zu zahlreichen lebenswichtigen Prozessen im Körper. Dr. Sebastian Busch erforscht mithilfe von Neutronen, wie dieses unscheinbare Molekül Proteinstrukturen formt, Medikamente ins Gehirn bringt und sogar Viren die Tür zu unseren Zellen öffnet. Verstehen wir diese Prozesse, eröffnen sich neue Wege in der Behandlung von Krankheiten wie Alzheimer oder Krebs. Erfahrt, warum Wasser so essenziell ist und wie es die Medizin revolutionieren könnte – bei diesem spannenden Vortrag!
Dr. Sebastian Busch, Helmholtz-Zentrum Hereon at the Heinz Maier-Leibnitz Zentrum
On our Open Day, 3 October, we cordially invite you to visit our information stands in the foyer of the TUM Department of Physics. Here you will have the opportunity to gain exciting insights into the world of modern neutron research.
At our information stands you will learn more about the Heinz Maier-Leibnitz Research Neutron Source (FRM II) and the associated Heinz Maier-Leibnitz Zentrum (MLZ). Experience how neutrons are used to analyse materials and what scientific breakthroughs can be achieved with them. You can also find out how our research neutron source works and what measures are taken to monitor the environment in order to measure radioactivity. Furthermore, you can find out about the radiation protection measures and tasks of our radiation protection team, which are taken to protect employees and the environment.
In addition, we will introduce you to the world's most intense positron source ‘NEPOMUC’, which is operated at the FRM II. Discover how these exotic particles are produced and which current areas of research deal with the investigation of positrons.
Of course, we also offer our youngest visitors exciting hands-on and information stands:
- Lego model of scientific instruments (TRISP, ANTARES)
- Model of the fuel element
- Short films
- Neutron throwing game for children
- Cloud chamber - makes natural radiation visible
- Measuring devices for determining radioactivity and exhibits for self-measurement
We look forward to your visit!

Become a scientist in a large-scale research facility! You want to discover the unknown and solve exciting puzzles? Together we will explore these question
- What are neutrons?
- What does a crystal have to do with a rainbow?
- How do neutrons help research new corona vaccines or drugs?
- Can you eat nitrogen?
In the special children's tour we will have a closer look at the neutron source and some experiments!
INFORMATION: Unfortunately, all places for our children’s tours are already fully booked for this year. We are very pleased about the great interest and hope to welcome you at a future event.
