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.
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.
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.
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.
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.
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.
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

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.

In 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.

Magnets are the unsung heroes in particle accelerators because they keep protons or electrons on track. But such magnets have very little in common with the small ones on the domestic fridge door. Quite a few of the magnets at PSI are heavier and bulkier than the fridge itself, yet despite this they are also masterpieces of precision and control.

The source of the proton beam at PSI is a retro-style Cockcroft-Walton linear accelerator. Since 1984 it has been the first acceleration stage for protons which are taken up to around 80 percent of the speed of light by two further ring accelerators. This has resulted in the generation of a significant proton beam over decades, and which has even held the world record as the highest performing beam since 1994 thanks to ongoing retrofitting.

The way that algae and plants respond to light has been reinterpreted based on results from recent experiments. Under particular lighting conditions during photosynthesis, the well-ordered stacking and alignment of light-sensitive membranes in the algae are disrupted. There is no significant movement of the membrane embedded light harvesting proteins, which rather become largely inactive. These new findings challenge widely accepted views of how algae respond to light where the light harvesting proteins were thought to move around the membranes.

For the electrons to reach the necessary energy level, their path in the linear accelerator needs to be absolutely straight. Even the slightest bend means a loss of energy, which the comparatively short SwissFEL linear accelerator cannot afford. Consequently, even the earth’s curvature needs to be balanced out while constructing the building, which not only requires state-of-the-art measurement technology, but also continuous monitoring.

8. November 2013Large Research Facilities SwissFEL
SwissFEL will create X-ray light with laser-like characteristics. The strong amplification of the light needed is produced by a process known as
micro-bunching– electron packets break up in the undulator into thin layers which emit light in phase. At the same time, another process called
seedingis being studied, in which one will be able to establish the properties of the light even more precisely.
15. August 2013Large Research Facilities SwissFEL
X-ray light is produced in SwissFEL when electrons accelerated in its linear accelerator are forced to follow a wavy path. This takes place within the undulators – regular arrangements of magnets that bend the electron beam. The whole undulator section will be 60 metres long.

A terahertz laser developed at the Paul Scherrer Institute makes it possible to control a material’s magnetisation precisely at a timescale of picoseconds. In their experiment, the researchers shone extremely short light pulses from the laser onto a magnetic material. The light pulse’s magnetic field was able to deflect the magnetic moments from their idle state in such a way that they exactly followed the change of the laser’s magnetic field with only a minor delay. The terahertz laser used in the experiment is one of the strongest of its kind in the world.

The manipulation and examination of irradiated and therefore radioactive objects, be they from nuclear power stations or research facilities, requires strict safety measures. Tests may only be conducted in so-called “hot cells”, where the radioactivity is hermetically enclosed and shielded behind concrete and lead walls up to 1 metre thick. In the hot cells of the PSI hot lab, the burnt-off fuel rods from the Swiss nuclear power stations are studied from a materials science perspective. The insights gained help nuclear power station operators to optimise the efficiency and safety of their plants. Besides this service, the hot lab is involved in several international research projects.

Inside the SwissFEL, electrons will be accelerated to almost the speed of light, then forced along a curved pathway by very powerful magnets, emitting X-ray light as they travel. SwissFEL is thus composed of an ‘electron gun’ (which generates the electron beam), an accelerator, and an undulator in which the electrons are guided along a wave-like path. An experimental area lies at the end of this track, where the light produced will be used to perform experiments.

Along its path, the beam first strikes one target, then the second, and then moves on to the lead target of the SINQ neutron source. Muons are generated by the collisions of protons with the carbon nuclei in the first two targets. PSI operates two muon targets because a single one could not supply enough muons for all the experiments being performed. The muons are guided with the aid of magnets to the individual measuring stations, of which there are currently six for experiments in solid-state physics using muons.
1. December 2009Matter and Material Research Using Synchrotron Light Large Research Facilities
The synchrotron light in the SLS is emitted from electrons, which move at a velocity of almost the speed of light along a circular path with an overall circumference of 288 metres. The synchrotron light is emitted tangentially to the trajectory of the electrons, i.e. in the same direction as sparks would fly from a grindstone, or a hammer from the hands of a hammer thrower.
The production of synchrotron radiation makes use of the fact that electrically charged particles emit light as they move along a curved path. Bending magnets keep the electrons on their curved track, as a magnetic field deflects fast-moving electrically-charged particles.

In the SINQ spallation source a beam of fast protons (at about 80 % of the speed of light) from the PSI proton accelerator facility strikes a block of lead (the Target). If a fast proton collides with a lead nucleus, the nucleus will be heated up and eject 10 to 20 neutrons. The neutrons set free by this method are extremely fast – much too fast for the experiments. In order to decelerate the neutrons after they have been generated, the whole target is placed in a tank filled with heavy water
