Scientists Use LCLS to See Photovoltaic Process in Action

LCLS News

A surprising atomic-scale wiggle underlies the way a special class of materials reacts to light, according to research that may lead to new devices for harvesting solar energy.
For decades, scientists have known that some ferroelectric materials – materials that possess a stable electrical polarization switchable by an external electric field – are also photovoltaic: They produce an electric voltage when exposed to light, just as solar cells do. But it was not clear how the light induced voltages in these materials.

Ultrafast Lasers at the Linac Coherent Light Source

Alan Fry

The Linac Coherent Light Source at SLAC is the world’s first hard X-ray free-electron laser, or FEL, and one of the most complex light sources ever developed. Its ultrashort pulses of X-ray laser light, a billion times brighter than any light source before it, are uniquely capable of probing the detailed structure and dynamics of atoms, molecules, and materials. But this brilliant beam is not the only laser at work in the LCLS. Other ultrafast lasers kick off the process that generates the X-ray laser beam and play an essential role in experiments at the LCLS.more...


Claudio Pellegrini: A Patriarch of the LCLS

Lori Ann White

"It takes a village," as Hillary Clinton famously wrote, "to raise a child." Similarly, says physicist Claudio Pellegrini, it takes an entire scientific community to create a ground-breaking new piece of technology—one that not only adds to the store of human knowledge through its use, but requires its designers to push back scientific and technological frontiers just to build it in the first place. The Linac Coherent Light Source is a case in point. more...


LCLS-II Test Undulator

Brad Plummer

This test undulator is on loan from Argonne National Laboratory and currently resides in SLAC's Building 26, where the Metrology Department's Magnetic Measurement Group is trying out measurement techniques to be used on the LCLS II project, a proposed second X-ray free-electron laser that would expand on SLAC's Linac Coherent Light Source. Originally built for the Advanced Photon Source lightsource at Argonne, this "hybrid" undulator uses permanent magnets interposed with steel poles, an arrangement which helps intensify the magentic field (and which creates the appearance of "teeth"). Unlike LCLS I, the LCLS II will use variable-gap undulators, like this one, in which the movable "jaws" can be opened or closed to alter the properties of X-rays the undulator generates. more...

Last Saturday brought perfect chamber-moving weather, and a handful of SLAC riggers, vacuum assembly personnel and scientists took full advantage of the conditions by moving the central piece of the Coherent X-ray Imaging instrument into the Far Experimental Hall of the Linac Coherent Light Source. The 4,000 pound, red girder and primary chamber assembly made their way to the FEH at one mile an hour, strapped to a flatbed trailer. There, the team guided the instrument down the tunnel incline and into the CXI hutch, the middle of three hutches in the FEH. Assembly crews will spend the next few weeks mounting a further complement of instruments and chambers to the girder in preparation for beam this December. more...
