Superconductivity
Superconductivity is the property of certain materials to conduct electricity without energy loss when they are cooled below a critical temperature.
An 0.5-mile-long stretch 30 feet underground below Interstate 280 in Menlo Park, California, is now colder than most places in the universe: -456 F. It houses a new particle accelerator that is part of a $1bn upgrade of SLAC’s X-ray laser LCLS. The new machine, LCLS-II, will be able to produce up to a million X-ray flashes per second – a world record for today’s most powerful X-ray light sources.
