Scientists at SLAC have found a new method to create coherent beams of twisted light – light that spirals around a central axis as it travels.

Dao Xiang, a SLAC accelerator physicist, has received an international award for his work on a technique for tuning an electron beam with a laser to produce X-ray pulses with more uniform and predictable properties.

Last Saturday marked the 40th anniversary of an historic event: In 1973, a team of research pioneers extracted hard X-rays for the first time from SLAC's SPEAR accelerator.

A tool developed half a century ago for sorting subatomic particles has been redesigned to measure X-ray laser pulses at SLAC's Linac Coherent Light Source (LCLS).

John Hill watched with eager anticipation as controllers ramped up the power systems driving SLAC's X-ray laser in an attempt to achieve the record high energies needed to make his experiment a runaway success.

Two SLAC physicists with decades of particle accelerator experience helped a Silicon Valley company design and build X-ray devices that scan cargo containers for nuclear materials and other hazards.

SLAC researchers have demonstrated for the first time how to produce pairs of X-ray laser pulses in slightly different wavelengths, or colors, with finely adjustable intervals between them – a feat that will allow them to watch molecular motion as...

'Self-seeding' promises to speed discoveries, add new scientific capabilities

In 1971, physicist Burton Richter of Stanford Linear Accelerator Center was building a new type of particle collider called a storage ring.
