Research Using Neutrons

At the Paul Scherrer Institute PSI, researchers together with a company have constructed a room that is one of the best magnetically shielded places on the earth. With its help, they want to solve the last mysteries of matter and answer a fundamental question: Why does matter - and thus why do we - exist at all?

Researchers at the Paul Scherrer Institute PSI have for the first time identified special nano-vortices in a material: antiferromagnetic skyrmions.

At the ultracold neutron source at PSI, researchers have measured a property of the neutron more precisely than ever before: its electric dipole moment. That's because the search is still on for an explanation of why, after the Big Bang, there was more matter than antimatter.

Traditionally, violins are varnished to protect them from humidity and other environmental influences. At PSI, a scientific team has investigated how different coatings affect the instrument. Under no circumstances, they found, should anyone try to do without varnish completely.

Radionuclides open up new options for treating cancer. Christian Rüegg, head of the Research with Neutrons and Muons Division at PSI, explains the significance of the Swiss Spallation Neutron Source SINQ at PSI.

At the neutron source SINQ, PSI researchers are producing special radionuclides that aid in the development of new and more effectively targeted cancer therapies. In this they collaborate closely with the clinics in the surrounding area.

A 3,500-year-old bronze sculpture is being examined at PSI's SINQ neutron source. This will enable conservators to get a unique view into the interior of the sensational find – and gain insights into how it was made.

For the first time, PSI researchers have used neutrons to visualise very strong magnetic fields that are up to one million times stronger than Earth's magnetic field. This now makes it possible to study magnets that are already installed in devices such as magnetic resonance tomography systems or alternators.

PSI researchers are helping the European space program: Their neutron imaging serves to ensure the quality of critical components for rocket launches.

In the Nuclear Energy and Safety Research Division at PSI, Johannes Bertsch focuses on the so-called cladding tubes that are used in nuclear power plants.

Electronics should get smaller, faster, and above all more energy-efficient. These themes are also present in several research groups at PSI. From incremental improvements to complete rethinking – who is currently working on what?

If you make electronic components smaller, they unfortunately get hotter. Also, we will soon reach the limit of technically feasible miniaturisation. At PSI, Gabriel Aeppli and Christian Rüegg are working on fundamentally new, physical solutions for better computers and data storage devices.

A team with three researchers from the ETH Domain has been awarded a prestigious EU grant. Today, they received the contract signed by the EU confirming the extraordinary 14 million euros funding. With it, they will investigate quantum effects which could become the backbone of future electronics.

Use of multiferroic materials promises more energy-efficient computers because in these, an electric field would suffice to achieve magnetic data storage. Researchers at PSI have now made such a material suitable for computer operating temperatures.

Shortly after the Big Bang, radioactive Beryllium-7 atoms were formed, which today, throughout the universe, they have long since decayed. A sample of beryllium-7 artificially produced at PSI has now helped researchers to better understand the first minutes of the universe.

Researchers from the Paul Scherrer Institute PSI, the University of Basel and Roche have used neutron imaging to investigate why cool storage is crucial for syringes pre-filled with a liquid medication.

The ABB facility in Wettingen got practical recommendations on increasing production of ceramic components. Researchers at the Paul Scherrer Institute PSI examined the components by means of neutron imaging. With the help of these images, ABB employees were able to see where there is still potential for process optimisation. This feasibility study was funded by the Hightech Zentrum Aargau.

Jean-Baptiste Mosset, winner of a Founder Fellowship at the Paul Scherrer Institute PSI, wants to commercialise a neutron detector to spot plutonium and uranium.

No evidence of dark matter made of axions – result of an experiment at the Paul Scherrer Institute PSI further constrains theories about the nature of dark matter.

Ancient metal objects are illuminated by neutrons at the Paul Scherrer Institute PSI. This enables researchers to discover what is hidden inside them, how they were made and how they can be preserved.
