They have two e-mail addresses, two offices, and two filing cabinets in two locations: Around 60 of the researchers at PSI are at the same time professors or lecturers at a Swiss university. PSI and the universities also profit from these researchers with double affiliations.
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.
Researchers at the PSI have made detailed 3-D X-ray images of a commercially available computer chip. In their experiment, they examined a small piece that they had cut out of the chip beforehand. This sample remained undamaged throughout the measurement. It is a major challenge for manufacturers to determine if, in the end, the structure of their chips conforms to the specifications. Thus these results represent one important application of an X-ray tomography method that the PSI researchers have been developing for several years.
For over 30 years, patients with a particular form of ocular tumour have been treated at PSI by means of proton irradiation. The tiny particles hit their target with millimetre precision, without endangering other structures of the eye. The irradiation facility OPTIS, developed at the PSI Center for Proton Therapy of the PSI, is a success story, considering that for more than 90 percent of the patients treated to date, the eye could be saved.
A new visitor’s station at PSI tells the story of a Swiss town that makes the change from a conventional energy supply to one with new renewable energy sources.
A pharmaceuticals manager at Roche for a long time, now he is the founder of a biotech firm on the campus of the Paul Scherrer Institute PSI: Michael Hennig knows the trends in the medical sector. In this interview he explains why the medicine of the future needs the innovation power of publicly funded research, and why he chose to locate his start-up leadXpro so close to PSI.
The Laboratory for Energy Systems Analysis at the Paul Scherrer Institute PSI is investigating how Switzerland’s electricity supply might look, up to the year 2050, under a variety of boundary conditions. On the basis of their calculations, the lab’s researchers are able to generate insights on possible future developments of the energy sector, for example, determine how an ambitious reduction in CO2 emissions could be achieved at the lowest possible cost.
Until now, the onset of copper production in South America was still unclear. Hardly any written records or artefacts from the early high cultures in Peru, Chile, and Bolivia have been preserved. Now, however, researchers of the Paul Scherrer Institute PSI in Villigen (Switzerland) have tracked down the evidence. Through analysis of ice from the Illimani glacier in the Bolivian Andes, they found out that copper was being mined and smelted in South America since around 700 BC.
Martin Ostermaier wanted to break out of the comfort zone of science. Now, instead of pipettes, the biochemist is dealing with investors and patent law.
Within Switzerland’s bio-waste a huge amount of precious energy is hidden. That’s because valuable methane, the main constituent of natural gas, can be obtained from it. With a technology developed at PSI, the yield of methane from bio-waste could be increased considerably in the future. A long-term test conducted in cooperation with Energie 360° at the Werdhölzli fermentation and wastewater treatment plant is expected to advance this technology further along its path to industrial use.
At the Paul Scherrer Institute PSI, cancer patients receive a treatment that is unique in Switzerland: proton therapy. This state-of-the-art form of radiation therapy against cancer has major advantages, compared to conventional irradiation, in terms of effectiveness and side-effects. The PSI has its own Center for Proton Therapy dedicated to this special treatment. Its pioneering work has not only helped several thousand patients, but also has fundamentally changed proton therapy worldwide.
Eighty percent of all products of the chemical industry are manufactured with catalytic processes. Catalysis is also indispensable in energy conversion and treatment of exhaust gases. Industry is always testing new substances and arrangements that could lead to new and better catalytic processes. Researchers of the Paul Scherrer Institute PSI in Villigen and ETH Zurich have now developed a method for improving the precision of such experiments, which may speed up the search for optimal solutions.
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.
Atmospheric scientist Julia Schmale is starting out on a three-month research cruise around the Antarctic. There she will be searching for the cleanest air still to be found on our planet.
At the PSI, researchers work with radioactivity every day in order to develop advanced treatment methods for patients. Naturally, they take special safety precautions working with a material that decays. It's a race against time. To make sure everything functions smoothly, a dedicated work group takes care of the infrastructure.
Doctors had discovered, behind Gabi Meier’s right eye, a tumour that surrounded the optic nerve. Only at the PSI was there still one possibility to treat the tumour in such a way as to preserve neighbouring structures and the eye. A few months after the proton treatment was over, I realised that I could see more and more, she said in an interview. “Just dimly, it’s true, but I could see! That was sensational!”
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.
In most cases, electricity is generated when water is heated and transformed into vapour. Vapour bubbles in the water play a decisive role in this process. Using computer simulation, researchers at the Paul Scherrer Institute have succeeded in representing the behaviour of vapour bubbles – and in making their performance more calculable.
On 25.11.1996, at the Paul Scherrer Institute PSI, the world’s first cancer patient was treated with a new irradiation method: the so-called spot-scanning technique for proton beams. What’s special about it: The beam has its effect only at the depth where the tumour is located; healthy tissue above and below it is preserved. The method, developed by PSI researchers, was a breakthrough at the time and quickly became a successful product.
Clouds consist of tiny droplets. These droplets form when water condenses around so-called aerosols – small particles in the atmosphere. To understand how in turn aerosols come into existence scientists have now created a comprehensive computer model simulation based on profound experimental data. This simulation revealed that in addition to sulphuric acid, two other substances are crucially involved in the formation of aerosols: organic compounds and ammonia. These results have now been published in the renowned journal Science.
