Multi-Scale Structural Biology

The aim of this workshop is to review state-of-the-art results in structural biology and to facilitate a community discussion on the challenges at current and upcoming facilities. Topics include but are not limited to X-ray diffraction, scattering, electron microscopy, and temperature-jump experiments for structural and cellular biology that can reveal insights in dynamics and function across multiple scales in space and time. The workshop will also include a panel discussion on current capabilities, challenges, and future instrumentation needs that leverages synergies amongst different sources (LCLS, SSRL, cryoEM, etc.)

Automated Analysis and Control for X-ray Science Experiments (PM)

As data volumes and velocity increase for upgraded user facilities, real-time analysis is key to making decisions during an experiment. Human-in-the-loop experiment workflows are often too slow to keep up with data rates and assistance via automation is needed to help scientists. This workshop includes computing solutions or technologies that help scientists automate the "control" of their experiments where control can mean managing data, analyzing data, adjusting experimental conditions (e.g. temperature and pressure, motors, detector configurations) or controlling the beam line itself. This workshop aims to explore automation technologies and related subjects such as algorithms, data science, AI, machine learning, and simulations related to experimental science that might eventually help with automation. Scientists are encouraged to submit use cases that include or have potential to include automation, especially machine learning.

MXAN:  Three Dimensional Structures for Metal Sites in Condensed Phases and in Catalysts

This workshop introduces the MXAN program, with which one can extract true three dimensional structures from the first 200 eV of an XAS spectrum, yielding both distances (±0.01 Å) and angles (±2⁰). MXAN takes advantage of extended continuum band theory to automatically calculate all the multiple scattering paths, leading to greater structural resolution than EXAFS analysis allows. Workshop attendees will introduced to the qualitative physics, will become familiar with the approach, and will learn how to apply the MXAN program with real data sets. The workshop combines presentations of method and scientific results in the morning, followed by a hands-on session to learn the code in more detail in the afternoon. MXAN can be especially useful in laser-pump, X-ray-probe experiments to derive the structure of transients.

LCLS-II Early Science & LCLS Science Campaigns (AM)

In 2020, LCLS will commission two new LCLS instruments (TMO and chemRIXS) and two new variable-gap undulators (SXU, HXU). This workshop will inform users about the commissioning plans and instrument capabilities of TMO and chemRIXS, and the plans for Early Science on these instruments in Run 18. Workshop participants will be encouraged to provide feedback, input, and ideas to refine the early science plans. This workshop will also provide an overview of the new LCLS Science Campaign Proposal process. Plans for initiating an attosecond science campaign in Run 18 will be presented.
