Research Using Neutrons
Cladding tubes and their properties
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.
Watching electrons and switching bits on
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?
Now it's time for something new
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.
EU grants 14 million to Swiss Researchers
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.
Making the impossible possible
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.
Material from PSI helps to check inconsistencies in the Big Bang theory
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.
Imaging the inside of injection needles with neutrons
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.
Imaging at Paul Scherrer Intitute helps to increase production at ABB site in Aargau
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.
More than a prototype
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.
Still no sign of dark matter
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.
From golden emperor to filled Buddha
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.
X-ray and neutron imaging for palaeontologists and archaeologists
Federica Marone illuminates objects with high-intensity X-ray beams, Eberhard Lehmann with neutrons. Both have used their methods to give palaeontologists and archaeologists a new view into the past.
From the garage to the world
In 1999, PSI researchers founded the spin-off firm SwissNeutronics. Today the company has a staff of 15, sells high-precision components to research institutions all over the world, and still is based in the small town of Klingnau – not far from PSI.
Successful for 20 years: Probing materials with particles
Whether they study materials for the electronics of the future, batteries, or swords from the Bronze Age — for 20 years researchers from a range of disciplines have been using the Swiss Spallation Neutron Source SINQ of the Paul Scherrer Institute PSI for their investigations. At a symposium on 18 April, researchers looked back on the facility's successes and presented plans for modernisation.
Towards energy-saving data storage
A new material could become the basis for future data storage devices, since it may enable significant reductions in energy demands in comparison to present-day hard drives. It is a material from the class of so-called magnetoelectric multiferroics, exhibiting the necessary magnetic properties even at room temperature.
ERC funding of €2.4 million for research on fundamental interactions in magnets
Christian Rüegg has been awarded a prestigious Consolidator Grant from the European Research Council (ERC). With this funding he will continue to investigate how the smallest magnetic building blocks of matter interact.
En route to better transformers
Thanks to an ultramodern research method, scientists have successfully looked inside transformers and observed the magnetic domains at work in the interior of a transformer’s iron core. Transformers are indispensable in regulating electricity both in industry and in domestic households. The current research results show that the new examination method can be profitably applied to develop more efficient transformers.
Zebra - a new instrument for the PSI
Interview with Oksana ZaharkoNew scientific questions demand ever better experimental equipment. In this interview, PSI researcher Oksana Zaharko reports on the challenges of setting up a new instrument for research with neutrons.
Neutrons reveal distribution of flux-tube islands
Usually, superconductors expel magnetic fields. In type II superconductors, however, thin channels – so-called flux tubes – are formed. The magnetic field is guided through these tubes while the rest of the material remains field-free and superconducting. In the metal niobium, the flux tubes bunch together into small islands that create complex patterns similar to those found in other fields of nature. A team of researchers from PSI and TU München were the first to conduct neutron experiments to study these patterns in niobium and determine the distribution of the islands in detail.
New method will enable most accurate neutron measurement yet
Our universe consists of significantly more matter than existing theories are able to explain. This is one of the great puzzles of modern science. One way to clarify this discrepancy is via the neutron’s so-called electric dipole moment. In an international collaboration, researchers at PSI have now devised a new method which will help determine this dipole moment more accurately than ever before.
