Laser pulse compression technology invented in the late 1980s developed high-power short-pulse laser techniques, enhancing laser intensity 10-million-fold in a quarter of a century. Scientists at Osaka University discovered a novel particle acceleration mechanism called ‘micro-bubble implosion,’ in which super-high energy hydrogen ions (relativistic protons) are emitted at the moment when bubbles shrink to atomic Read more about A novel particle acceleration mechanism called ‘micro-bubble implosion,[…]
