Join Ryan Coffee as he presents the first pump-probe experiment. The LCLS free-electron x-ray laser is the first coherent radiation source capable of saturating K-shell photoionization for second row elements. Our experiment was the first opportunity to study multiple core-hole processes in aligned molecules. We used the tight focus of the LCLS in the High Field Physics instrument to create double-core vacancies in nitrogen molecules. more...

University of Western Michigan physicist Nora Berrah wrapped up her research group's five-day run on the Linac Coherent Light Source on October 20. Their project marked the first time that the powerful X-ray laser had been used to study molecules. It was a complex experiment, and Berrah readily acknowledged that the work wouldn't have been possible without the teamwork and cooperation of the LCLS Atomic, Molecular and Optical instrument scientists and engineers. But she also gave a big nod to an more...

While not the smallest lettering ever created, the tiny initials "LCLS" have been written with what may be the world's most potent pen. Etched into boron carbide, a super-hard substance used in accelerator shielding and body armor, the lettering has helped researchers at SLAC National Accelerator Laboratory explore the capabilities of the world's first hard X-ray laser, the Linac Coherent Light Source. more...

The LCLS offers a powerful route to recovering the structure of individual biomolecules from random diffraction snapshots of series of identical molecules. However, biological molecules can assume a variety of conformations. Mapping the conformational heterogeneity of macromolecules presents a formidable challenge to X-ray crystallography, single-molecule coherent diffraction, and cryo-electron microscopy. more...

The LCLS has had a dramatic start up at its shortest wavelength (1.5 Å) reaching saturation on April 14, 2009 with 1.1 mJ per pulse energy. This is the baseline performance, but there is room for more and this workshop will discuss the scientific opportunities that near term options for enhanced performance (wavelength reach, polarization, pulse duration, multiplexing options, etc.) will enable as well as the science drivers for the long term development of LCLS. more...

Even before the Linac Coherent Light Source achieved lasing, the first call for proposals for beam time went out. Twenty-eight proposals were submitted by 219 scientists from 16 countries to get beam time on the Atomic, Molecular and Optical science instrument in fall 2009. An external proposal review panel selected the 11 best proposals. Each experimental team is sending a team member to SLAC in July to participate in the commissioning of the instrument and there will be first beam to the users more...
