Satellite Events (October 1-2, 2013)


The workshop for Inverse Compton Source (ICS) will explore and develop a scientific case for an ICS at SLAC. The ICS is a compact x-ray source capable of generating high energy photons (tens of keV to 100keV+ , potentially MeV) at high brightness with shot-to-shot polarization and energy tunability, complementing the SSRL and the LCLS. The high energy photons enable mesocale science in fields ranging from geology to bioimaging, in which penetration through thick samples is essential. Implementation of microscale full field imaging with the ICS will complement the nanoscale x-ray microscopy capabilities at SSRL and electron microscopy facilities on the Stanford campus, enabling multiple-length-scale characterization capability at SLAC/Stanford.  The shot-to-shot polarization-tunability may open opportunities in material studies, and the generation of MeV level photons, enabling even larger penetration lengths, may lead to potential applications in homeland security.  The workshop will bring together scientists from different backgrounds and encourage discussion of scientific areas that would benefit from the availability of high energy, tunable x-rays from a compact source. Ideas and discussions from all research fields are welcome.

In light of a rapidly changing global climate, environmental carbon science is at the forefront of investigations in the scientific, political and socio-economic arenas.  In particular, the role of microbes and minerals in precipitating, degrading and preserving carbon is receiving increasing attention as a primary process controlling the capacity of sediments and soils for long-term sequestration. Natural organic matter in soils and subsurface sediments comprises the largest pool of carbon in Earth's near-surface, larger than in the atmosphere and marine photic zone. This workshop will bring together scientists investigating the biotic and abiotic forces impacting the carbon cycle using synchrotron radiation and other complementary techniques.  The goal of the workshop is to develop scientific interest, expertise, and interest in this critical field by fostering collaborations and target needs for increasing the value of synchrotron techniques to carbon science.

The newly commissioned Matter in Extreme Conditions (MEC) Instrument at LCLS has made great strides towards characterizing shock waves in solids with high precision x-ray scattering techniques.  These studies provide for the first time a complete data set with accurate measurements of the plasma parameters and the structure of matter at high energy density.  With the ultra short pulse laser capability being upgraded to higher peak power, new pump-probe experiments will become possible.  In this workshop, we bring together domestic and international experts in this field to discuss recent experiments at MEC and the new physics area where the high intensity optical laser and the LCLS x-ray beam can providing either target drive or probe. See SLAC Today article. Register for the High Power Laser Workshop. Program


As experimental concept and execution becomes increasingly complex across the spectrum of user-driven light sources, data analysis becomes more complicated and the urgency of completing an experiment on the first attempt grows.  It has become apparent that simulation of the expected signal from such experiments can increase the likelihood of success of a particular experiment and the efficiency of a facility as a whole.  In this workshop, we bring together representatives from domestic and international facilities to discuss the driving principles of and the need for a modular and user-friendly, source-to-detector simulation framework for x-ray experimentation.

Synchrotron-based techniques are gaining momentum as a powerful approach to exploring the cycling and speciation of metals in systems traditionally outside the scope of molecular scale techniques. These novel approaches are extrapolating the molecular scale information gleaned from synchrotron studies to understand macro-scale processes and biogeochemical interactions ranging from the global ocean to the microbe-metal interface and over time scales spanning millions of years. This session will bring together scientists whose research highlights the broad spectrum of questions that are being answered by using various synchrotron-based approaches.

Operation of a synchrotron in low-alpha mode or by using advanced RF cavities opens up the possibility to study dynamic phenomena with 10ps time resolution or better without losing significant brightness or even without disturbing regular operation. Such an operation will enable scientific programs to bridge the gap between time resolved studies in regular operation (100ps) and ultrafast studies using LCLS (<1ps). During this workshop we will address the current state of the program at SSRL as well as future scientific directions that are enabled by such a source. We will also evaluate the possibility for new detection schemes that are capable of collecting time resolved data in real time during low alpha operation of SSRL.

Serial crystallography is a growing field at LCLS with a rapidly growing user base.  One of the key bottlenecks is being able to rapidly analyze large datasets to arrive at structure factors for structure solution and refinement.  This workshop will focus on analysis tools for serial crystallography, providing an overview of available computational tools and software as well as addressing key issues in data processing and data quality assessment compared to 'normal' synchrotron crystallography. Live demonstrations and tutorials of the software packages will be performed where possible to help new users.
