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.
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. 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.
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.
The Brookhaven National Laboratory scientist was the leader of a research team that had come from Illinois, Germany, Switzerland and England to use the Linac Coherent Light Source (LCLS), and this was their last day. They would get only one shot.
