Copper blasted into a million-degree plasma strips away 22 electrons in a flash before atoms recover

When laser flashes hit matter, electrons are knocked off their orbits around the atomic nuclei. This can generate extremely hot plasmas composed of charged particles—ions and electrons. Researchers at HZDR have now observed this ionization process in more detail than ever before. To do so, they combined two state-of-the-art lasers: the X-ray free-electron laser and the high-intensity optical laser
