This is the first mini–particle accelerator to power a laser

Posted by in category: particle physics

For 2 decades, physicists have strived to miniaturize particle accelerators—the huge machines that serve as atom smashers and x-ray sources. That effort just took a big step, as physicists in China used a small “plasma wakefield accelerator” to power a type of laser called a free-electron laser (FEL). The 12-meter-long FEL isn’t nearly as good as its kilometers-long predecessors. Still, other researchers say the experiment marks a major advance in miniaccelerators.

Experiment demonstrates improvement in particle beams from plasma-based accelerators.
