Wednesday, Sept 27

Several parallel workshops are being planned for Wednesday, September 27, 2017. This program will be updated as details are finalized.

Morning Sessions

Afternoon Sessions


  • Additive Manufacturing
    • Organizers:  Johanna Nelson Weker, Kevin Stone (SLAC/SSRL)
    • Metal additive manufacturing (AM) builds 3D components by selectively melting metal precursors to build a component layer-by-layer. Currently, widespread adoption of AM is hindered by the lack of understanding between the processing parameters and the resulting evolution of composition and microstructure of printed parts. Models are ill equipped to accurately predict the performance of a part and therefore cannot be used to qualify builds. X-ray characterization of the melt pool and its resolidification during the AM process promise to provide valuable knowledge that can be used to inform and improve existing modeling efforts and thereby accelerate the process development and qualification time for additively manufactured components.
    • Invited Speakers: 
      Wayne King, Lawrence Livermore National Laboratory
      Tao Sun, Argonne National Laboratory/APS


  • First Experiments for LCLS-II: From Early Science to the PRP
    • Organizers: Mike Minitti, David Fritz, Robert Schoenlein (SLAC/LCLS)
    • The LCLS-II Instrument Development Team, in coordination with the Instrument Advisory Panels and with User input from previous workshops, have identified and refined a representative subset of “early science” experimental campaigns. These campaigns were translated into specific development plans that will drive the definition and phased implementation of the newly delivered instrument suites.  Updates on the progress of each of the three new experimental suites, as well as the Facility’s approach to commission, transfer to operations, and perform the First Experiments will be presented.


  • Probing Structure and Chemistry of Surfaces using Hard X-ray Methods
    • Organizers:  Simon Bare, Apurva Mehta, John Bargar (SLAC/SSRL)
    • Thin film devices and interfacial chemistry have long been of scientific and technological importance.  The properties of this ultrathin films and especially the interfacial surfaces are distinctly different from those of the bulk material.  A probe of atomic scale structure and chemistry of these surfaces (and thin films) under operational conditions is critical for gaining a fuller understanding how these surfaces perform the chemistry and the thin film device function.  In this workshop we will discuss various hard x-ray scattering and spectroscopic techniques, including challenges they pose and strategies needed to employ them to effectively probe them under operando conditions, to understand how they function and how they fail.
    • Invited Speakers:
      Young-Shin Jun, Washington University, St. Louis
      Stefan Vajda, Argonne National Laboratory
      Anders Filsøe Pedersen, Technical University of Denmark
      Reshma R Rao, MIT
      Trevor Petach, Stanford University
      Paul Fenter, Argonne National Laboratory
      Jeremy Feaster, Stanford University


  • New Methods for Room Temperature Serial Crystallography at SSRL
    • Organizers:  Aina Cohen, Raymond Sierra, Artem Lyubimov (SLAC)
    • Further details coming soon

  • Accelerator Performance Developments
    • Organizer: Franz-Joseph Decker
    • After the 6-month downtime for the BSY reconfiguration, the LCLS accelerator is performing well with photon pulses up to 6 mJ at 9 keV.  New developments are on the way, and improved understanding of transverse wakefield kicks is helping to enhance multi-bunch experiments.


  • Feature Extraction for LCLS-II
    • Organizers: Paul Christopher O'Grady, Jana Thayer
    • The high-rates associated with LCLS-II will produce data volumes of ~200GB/s in 2020 with significant increases in subsequent years.  To control computing costs/complexity and analysis turnaround-time, the relevant science features will have to be extracted from the data in real-time using software and firmware algorithms.  This workshop will discuss algorithms and infrastructure needed to reduce the data volume by a factor of 10.
    • SLAC Speakers:
      Chris O’Grady, Chuck Yoon, Mikhail Dubrovin, Silke Nelson, Sioan Zohar, Clemens Weninger, Tim van Driel
    • Invited Speakers:
      Aaron Brewster, Lawrence Berkeley National Laboratory
      Anton Barty, CFEL


  • Ultrasensitive Electronic Structure Detection in (Bio)Chemistry and Catalysis
    • Organizers:  Dimosthenis Sokaras, Dennis Nordlund, Thomas Kroll (SLAC/SSRL)
    • Capturing valency, spin and symmetry of active centers in chemical reactions is at the heart of our quest to decipher the most important processes in biology and industrial catalysis. SSRL is uniquely positioned to provide a powerful platform for comprehensive characterization using ultrasensitive core-level spectroscopy detection techniques applicable across the periodic table and in many different environments. This workshop will focus on technical advances with ultrasensitive instrumentation in both the hard and soft x-ray regions, two breakout session in bio-chemistry and chemical catalysis, followed by a panel on how the systems (soft and hard x-ray spectroscopy setups and by extension lcls) can be integrated into a powerful platform.
