Tabletop particle blaster: How tiny nozzles and lasers could replace giant accelerators

Osaka, Japan (SPX) Jun 04, 2025
Proton beams with giga-electron-volt (GeV) energies-once thought to be achievable only with massive particle accelerators-may soon be generated in compact setups thanks to a breakthrough by researchers at The University of Osaka. A team led by Professor Masakatsu Murakami has developed a novel concept called micronozzle acceleration (MNA). By designing a microtarget with tiny nozzle-like f
