News & Stories from PSI
X-rays show how quasiparticles interact in solids
Thanks to a new experimental technique at SwissFEL, researchers uncover the interplay between electronic, magnetic, and lattice excitations in a solid.
New method for inspecting fuel rods
PSI researchers have successfully used a new method to analyse the cladding tubes of spent fuel rods from nuclear reactors at very high resolution for the first time. They found that the cladding tubes remained leak-tight.
Nobel Prize meets PSI research
This year’s Nobel Prize in Medicine honours optogenetics: this method uses light to selectively control processes in cells. Researchers at PSI are advancing the field further.
Quality over energy in X-ray production
High-quality electron beams pave the way for more compact and affordable X-ray free-electron lasers.
