Simulations for More Efficient Power Stations

Energy and Environment Nuclear Power Plant Safety

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.

20 years of high-precision combat against cancer

Medical Science Human Health

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.
