The US Department of Energy's SLAC National Accelerator Laboratory emitted its first X-rays using the upgraded Linac Coherent Light Source (LCLS) X-ray free-electron laser (XFEL). The lab website says the LCLS-II cost $1.1 million and generates a million X-ray flashes per second, making it 8,000 times faster than its predecessor. Merge ideas of an advanced laboratory and a massive laser, and you'd probably think it's about a movie villain's superweapon. Yet, this X-ray laser could shine the way toward unprecedented advancements in biology, chemistry, physics, and other branches of science. It lets scientists absorb undetectable phenomena in real time, letting us learn more about them....Keep on reading: World’s most powerful X-ray laser fired recently
