Focus of our work

Neutrons for Users - (C) W. Schürmann,TUM

Neutrons for Users

We operate neutron scattering instruments at the best neutron sources in the world and we offer access to them for a large user community.

Neutron for Research

Neutrons for Research

We use neutrons as microscopic probes to conduct research on soft and condensed matter, life science and energy materials.

Neutron Techniques

Neutron Techniques

We design, build and install new instruments and neutron sources at neutron facilities. With our research we push the boundaries of available techniques and develop new methods for research with neutrons.

Neutron Landscape

We are connected to a worldwide network of leading neutron sources and are members of the League of Advanced European Neutron Sources.



European Spallation Source (ESS)

The world's most powerful neutron source is currently built in Lund and Jülich will be part of it. JCNS aims to deliver first-class instruments and components and to contribute with its competence and decades of experience in neu- tron science and methodology to make the ESS a success.


High-Brilliance Neutron Source

The project high brilliance accelerator-based neutron source HBS represents a unique future infrastructure for neutron analysis (imaging methods and scattering) to be used in a multitude of scientific disciplines such as physics, chemistry, biology, geology, material and engineering science.

Instrument Technology

The Instrument technology department develops new solutions for the automation of neutron scattering instruments and supports the instrument teams during construction and operation.

Reaktor FRM II

JCNS Outstations

JCNS operates neutron instruments at the sources MLZ, ILL and SNS under the motto the best instrument at the best sources.


Neutron SimLab

The Neutron SimLab provides support to the users of the JCNS instruments for neutron scattering data analysis, notably through the development of materials-specific mathematical models and numerical methods.

Science Office

The Science Office supports the directors in their tasks like in the preparation of strategic decisions as well as in networking and public relations work. Together with the administration the Science Office manages the EU third-party projects.


User Office

The Jülich Centre for Neutron Science JCNS offers access to dedicated neutron scattering instruments for users. Users can apply twice a year for beam time at instruments at MLZ, ILL and SNS.

News and Events


Neutrons detect clogs in pipelines

Neutrons are the perfect probe for detecting plugs in oil pipelines, as measurements at the Heinz Maier-Leibnitz Research Neutron Source (FRM II) in Garching have shown. The FaNGAS spectrometer operated by researchers at the Jülich Centre for Neutron Science (JCNS) played an important role in the scientific investigations. In practice, a mobile detector with a small neutron source will move back and forth along the pipeline to look for plugs.

Alterations in the Brain Under the Neutron Magnifying Glass

The brain is the centre of our nervous system - structural changes are often involved in neurological diseases and mental disorders. A team from Forschungszentrum Jülich has now developed a neutron-based method at the Heinz Maier-Leibnitz Zentrum (MLZ) to study brain slices and gain a better understanding of these types of diseases.
