Scientists developed a highly accurate optical ion clock, improving time measurement precision by 1,000 times.

The typical high-power ion laser of five years ago had a mean time-to-failure of about 2,000 hours. “If you think about a 24–7 operation, that's almost impractical,” says Schulze.

The development of laser–plasma accelerators began in the early 1980s, inspired by the pioneering work of Tajima and Dawson ... be generated by separating the ion and electron charges with ...
