2013 was another exciting year for LCLS, with a record number of new publications and new experiments. By employing novel X-ray optics that allow us to share the LCLS beam between instruments, we can now perform two experiments simultaneously in some cases. This way we are able to carry out 20 percent more experiments. This is very welcome news for the scientific community, as their demand for LCLS time is still steadily rising.

"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.

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.

The Linac Coherent Light Source beam will pack a wallop, providing 10 trillion X-ray photons in a flash of about 100 femtoseconds. For comparison, it takes today's best storage-ring-based synchrotron radiation facilities a full second to provide that many photons. Beginning next spring, researchers will begin to conduct experiments with these powerful bursts of X-ray light using the Soft X-Ray instrument, located on the second LCLS beamline to begin operation.

The Coherent X-ray Imaging instrument, the fourth scientific instrument to be installed at the Linac Coherent Light Source, will view single objects smaller than a micron, or one millionth of a meter—tiny. But even better than that, it may be the first X-ray instrument ever to do so for individual biological molecules when it comes online in 2011.
Monday, April 27, 2009
The Linac Coherent Light Source will pack a wallop. When it begins operation later this year, the LCLS will provide 10 trillion X-ray photons in a flash of about 100 femtoseconds—a quadrillion times faster than accomplished by today's best storage-ring-based synchrotron lightsources. When these powerful bursts of X-ray light reach the LCLS Far Experimental Hall in 2012, they will for the first time encounter the X-Ray Correlation Spectroscopy instrument, XCS for short. Using the powerful LCLS beam and a new extension of an experimental technique, the XCS will allow researchers to observe dynamical interactions within molecules on very short time scales.
Tuesday, March 03, 2009
After journeying more than 100 meters through undulators and diagnostic equipment, X-rays from the Linac Coherent Light Source will wiggle into the subterranean Near Experimental Hall and, beginning in 2010, zip into the X-ray Pump Probe science instrument. There they will meet a sample undergoing a reaction or in an excited state and, like a camera flash in a dark room, light the sample so that researchers can photograph it in detail.
Tuesday, February 10, 2009
When the Linac Coherent Light Source starts producing the world's first hard X-ray laser pulses later this year, they will all be headed to one place: the Atomic, Molecular and Optical science instrument. A complex creature comprising spectrometers, focusing optics, and a synchronized high-power optical laser, the AMO will be the first instrument in operation at LCLS—and the only one until March 2010.
