Fourteen workshops are scheduled during the four-day event. The workshops, including opportunities for contributed talks (designated with "*"), are summarized below.

Oct. 1: *Exploring an Inverse Compton Source (ICS) at SLAC. Organizers: Yijin Liu, Anne Sakdinawat, Mike Toney. 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.

Call for abstracts for ICS contributed talks: Scientific cases that would benefit from the availability of a compact, tunable high energy X-ray source will be discussed at this workshop. We have a few spots open for contributed talks (~20 minutes each), and we invite interested scientists to send us abstracts by Sept. 17. Ideas and discussions from all research fields are welcome.

Oct. 1: Integrating Synchrotron Techniques into Environmental Carbon Science. Organizers: Colleen Hansel, John Bargar. 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.

Oct. 1: X-ray Spectroscopy for Chemical Catalysis. Organizers: Mali Balasubramanian, Tsu-Chien Weng and Jun-Sik Lee. This workshop will discuss how the chemical catalysis program at SSRL can address the critical needs from the chemical catalysis community during the “dark period” between NSLS shutdown and NSLS-II.

Oct. 1: MicroXAS Imaging with SSRL's New 2-5 keV Beam Line 14-3. Organizer: Sam Webb. Beam Line 14-3 opens a new dimension of imaging and spectroscopy at SSRL, allowing micron sized imaging beams from 2-5 keV. This allows microprobe imaging and spectroscopy at the K edges for elements such as phosphorous, sulfur, chlorine and calcium, as well as imaging at the L edges for difficult elements such as antimony, cadmium and tellurium. This workshop will introduce the new beam lines to users and highlight some of the exciting recent scientific examples collected during commissioning.

Oct. 1: New Directions for High-Energy Density (HED) Physics at the LCLS Matter in Extreme Conditions (MEC) Instrument. Organizers: Siegfried Glenzer, Phil Heimann. 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 ultrashort 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.

Oct. 1: Toward a Modular Framework for Lightsource Experiment Simulation. Organizer: Garth Williams. 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.

Oct. 2: *AMO Instrument Update: Opportunities for New Science. Organizer: Christoph Bostedt. This workshop will discuss the recent and future improvements in the AMO hutch. A first experience and performance report of the new split and delay unit will be given. The new AMO imaging and spectroscopy capabilities (LAMP instrument) to be commissioned in late 2013 will be presented, and upgrade and improvement plans will be discussed.

Researchers with novel results or ideas concerning either the new imaging and spectroscopy capabilities provided by the LAMP chamber and/or pump-probe capabilities provided by the recently commissioned x-ray split and delay unit are encouraged to contact the organizers (C. Bostedt and J. Bozek) by Sept. 17 for the opportunity to present at the workshop.

Oct. 2: LCLS Data Analysis. Organizer: Amedeo Perazzo. This workshop focuses on practical training and simulations of data collection, diagnostics, analysis and interpretation.

Oct. 2: LCLS Detectors. Organizers: Gabriella Carini. This workshop will provide a short overview of basic detection principles and systems available at LCLS. Hands-on tutorials on CSPADs will follow and a final outlook on detector plans will conclude this half-day workshop dedicated to LCLS detectors. Participants will get an introduction into how to take and apply calibration data, use online monitoring to assess their data and tune their experimental setup in real time, etc. The goal of the workshop is to provide a basic training on detectors for FELs. By attending this workshop, users will learn how to efficiently collect good quality data with the CSPADs. The  information provided will help users to write proposals and design their experiments at LCLS.

Oct. 2: Synchrotron Techniques in Metal Biogeochemistry: Across Time and Spatial Scales. Organizers: Colleen Hansel, John Bargar. 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.

Oct. 4: Frontiers in Quantum Solids: Combining Soft X-rays and Ultra-fast Techniques. Organizers: Bill Schlotter, Josh Turner. This workshop focuses on providing potential users with an understanding of how the SXR instrument can enable new discoveries in their scientific field. The morning session will focus on current capabilities and instrumentation, as well as planned and envisioned instruments. During the afternoon invited and contributed talks will be presented which include interesting or new results from different fields that use soft X-rays. These will focus on sharing new scientific results, not necessarily in work at an FEL source, and explaining what future capabilities are important for realizing their goals for future experiments.

Oct. 4: Software for Serial Crystallography Data Analysis. Organizers: Anton Barty, Thomas White, Marc Messerschmidt. 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. The workshop is intended to be accessible to new users who wish to learn about serial crystallography data processing, as well as experienced users wishing to learn more about the range of available analysis tools and methods. Live demonstrations and tutorials of the software packages will be performed where possible to help new users.

Oct. 4: Scientific Opportunities using High Repetition Rate X-ray Sources with 1-10 ps Bunch Length. Organizers: Hendrik Ohldag, Apurva Mehta. 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.

Oct. 4: Early Career Scientist Associate Forum. Organizers: Hae Ja Lee, Andre Schleife. The first Joint SLAC-LLNL-LBL Postdoc Meeting will be held in conjunction with the 2013 LCLS/SSRL Users' Meeting on Oct. 4. During this half-day meeting which is aimed at postdoctoral researchers across all fields, participants will have the opportunity for scientific exchange, establishing collaborations, and exploring common or complementary areas of research interest. It is our goal to make use of the close proximity and the scientific overlap of SLAC, Lawrence Livermore National Laboratory and Lawrence Berkeley National Laboratory. At the same time this meeting will be a showcase for the excellent research carried out by young researchers at each institution. There will be scientific presentations with ample of time for discussion to efficiently connect all participants.
