Large Research Facilities
Sometimes, one needs unusually large pieces of equipment to look at the smallest of objects – because only these large machines or facilities can generate the
probes that are needed to examine matter in such a way that the information being sought can be obtained. PSI maintains a number of such facilities, making them available as a service for other institutions, but also using them for its own research. These facilities are unique within Switzerland, and PSI is the only location in the world for some of the facilities

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.
How do dye-sensitised solar cells work, and what's behind the brilliant new mobile phone displays? The ultrashort X-ray pulses at SwissFEL reveal the chemical reactions that take place inside these devices and could help to make them even more efficient and cost-effective.
On the path to new high-performance transistors
The electronics industry expects a novel high-performance transistor made of gallium nitride to offer considerable advantages over present-day high-frequency transistors. Yet many fundamental properties of the material remain unknown. Now, for the first time, researchers at the Paul Scherrer Institute PSI have observed electrons while they were flowing in this promising transistor. For that they used one of the world's best sources of soft X-rays at PSI's Swiss Light Source SLS.
Movie directors with extra roles
Data storage devices based on novel materials are expected to make it possible to record information in a smaller space, at higher speed, and with greater energy efficiency than ever before. Movies shot with the X-ray laser show what happens inside potential new storage media, as well as how the processes by which the material switches between two states can be optimised.
Hollywood in the Würenlingen woods
With the X-ray laser SwissFEL, researchers at PSI want to produce movies of biomolecules in action. This can reveal how our eyes function or how new drugs work.
First experiment at SwissFEL carried out successfully
The years of careful planning and construction have paid off: At the newest large-scale research facility of the Paul Scherrer Institute PSI – the X-ray free-electron laser SwissFEL – the first experiment has been carried out successfully. With that, two goals have been achieved: First, a new scientific result is already expected. Second, the interaction of the many individual components of the highly complex facility is being optimised.
Research experience from California benefits Swiss X-ray free-electron laser SwissFEL
An X-ray free-electron laser (XFEL) is capable of visualizing extremely fast structural and electronic processes. Pilot experiments will take place at the PSI's Swiss Free-Electron Laser (SwissFEL) from the end of 2017 on. Two current publications in Science and Nature Communications demonstrate the kind of outstanding scientific work that is enabled by such facilities. The work was carried out at the Linac Coherent Light Source (LCLS) in California. Two of the leading authors behind these studies have now relocated to the PSI in order to share their expertise as SwissFEL expands its capabilities.
Injector 2: a pre-accelerator for protons
As fundamental building blocks of matter, protons are part of all the things that surround us. At the Paul Scherrer Institute PSI, though, they step out of their usual role and are deployed to generate other particles, namely neutrons and muons, which are then used to study materials. But for that, the protons first have to be accelerated. An important role in this is played by a three-stage accelerator facility, in the middle of which stands the accelerator known as Injector 2.
To the limits of the feasible
The company Daetwyler made the undulators for the X-ray free-electron laser SwissFEL of the Paul Scherrer Institute PSI, to a precision of one-tenth of the width of a hair.
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.
Second beamline for SwissFEL
This year the first pilot experiments are starting at the X-ray free-electron laser SwissFEL. The X-ray light generated by SwissFEL will enable a broad spectrum of experiments. Beginning in 2020, a second beamline will provide for a still greater variety.
Today, on 5 December 2016, the Paul Scherrer Institute PSI held an inauguration ceremony for its new large-scale research facility SwissFEL, with Johann N. Schneider-Ammann, President of the Swiss Confederation, in attendance.
Physicists at the PSI’s large-scale research facilities are thinking beyond the Nobel Prize theories
This year’s Nobel Prize for Physics goes to David Thouless, Duncan Haldane, and Michael Kosterlitz. The Academy also cited, in its background report, experiments carried out by Michel Kenzelmann, who today is a laboratory head at the PSI. He and other researchers at the PSI continue to do experiments based on the theories now honoured by the Nobel Prize.
SwissFEL in the home stretch: The first electrons are here
SwissFEL building, 24 August 2016: In the control room above the beam tunnel of the X-ray free-electron laser SwissFEL, the atmosphere is intense and focussed. Marco Pedrozzi’s team has big plans for this late August afternoon. The last adjustments have been made — it’s time to press the big button and start up the electron source. The goal: SwissFEL should generate its first electrons. A report.
Catching proteins in the act
Proteins are indispensable building blocks of life. They play a vital role in many biological processes. Researchers have now been able to show how the ultrafast processes by which proteins do their work can be studied with free-electron X-ray lasers such as SwissFEL at the Paul Scherrer Institute PSI. Free-electron X-ray lasers generate extremely short and intense pulses of X-ray light. Currently there are just two such facilities in operation, worldwide. The results were published in the scientific journal Nature Communications.
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.
Five hundred thousand times less likely than winning the lottery
Measuring the rarity of a particle decayIn the so-called MEG experiment at the PSI, researchers are searching for an extremely rare decay signature from a certain kind of elementary particles known as muons. More precisely, they are quantifying its improbability. According to their latest number, this decay occurs less than once in 2.4 trillion events. By means of this result, theoretical physicists can sort out which of their approaches to describing the universe will hold up against reality.
Cooperation with nature
With SwissFEL, a new landscape takes shapeBarely completed, the building housing the X-ray free-electron laser SwissFEL has disappeared again beneath a mound of earth. Since then, planting and landscaping have been under way on and around this major research facility of the Paul Scherrer Institute PSI. Its special location, in a forest, demands that SwissFEL be integrated in an environmentally appropriate way. So the facility is, from the outside, nearly invisible. And rare animals and plants have gained new living space.
To the beam tunnel
Since the autumn of 2015, the SwissFEL beam tunnel has been filling up with the machine components for the new PSI large research facility. Piece by piece, the pre-assembled components are being brought to their final destination.
