Researchers Demonstrate 'Accelerator on a Chip'
SLAC Scientists Create Twisted Light
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. It has the potential to generate twisted light in shorter pulses, higher intensities and a much wider range of wavelengths, including X-rays, than is currently possible.
SPEAR-heading X-ray Science for 40 Years
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. Like X-rays from an X-ray tube, the radiation generated by SPEAR can deeply penetrate a large variety of materials and probe their inner structures. However, SPEAR's X-rays are significantly more intense and unlock the possibility for brand new science.
Shedding Light
In 1971, physicist Burton Richter of Stanford Linear Accelerator Center was building a new type of particle collider called a storage ring. The lab’s two-mile-long linear accelerator—housed in what was then the longest building in the world—would shoot electrons and their antimatter twins, called positrons, into the 80-meter-diameter Stanford Positron Electron Accelerating Ring, and SPEAR would set the beams of particles on a collision course. Richter and his colleagues stood by to examine the debris to see what discoveries came out.
