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.

Waves of magnetic excitation sweep through this exciting new material whether it’s in superconducting mode or not – another possible clue to how unconventional superconductors carry electric current with no loss.
A muon, center, spins like a top within the atomic lattice of a thin film of superconducting nickelate. These elementary particles can sense the magnetic field created by the spins of electrons up to a billionth of a meter away...
Scientists discover superconductivity and charge density waves are intrinsically interconnected at the nanoscopic level, a new understanding that could help lead to the next generation of electronics and computers.
A half-mile-long stretch of tunnel in Menlo Park, California is now colder than most of the universe. It houses a new superconducting particle accelerator, part of an upgrade project to the Linac Coherent Light Source (LCLS) X-ray free-electron laser.
Scientists discover that triggering superconductivity with a flash of light involves the same fundamental physics that are at work in the more stable states needed for devices, opening a new path toward producing room-temperature superconductivity.
Spawned by the spins of electrons in magnetic materials, these tiny whirlpools behave like independent particles and could be the future of computing. Experiments with SLAC’s X-ray laser are revealing their secrets.
