LCLS-II Early Science - Part II
Location: Kavli Auditorium

  • This workshop will focus on early science opportunities for LCLS-II, specifically the instruments NEH 1.1 (NAMASTE and DReaM) and the NEH 2.2 instrument (LJE). Speakers will be invited to present ideas of the most compelling science that will exploit these instruments in the areas of fundamental charge dynamics in isolated molecules, and coupled electronic and nuclear dynamics in molecular assemblies. Brief overviews of the capabilities of the instruments will be provided, and the early science process for LCLS-II will be presented.

Machine Learning for X-ray Science:  From machine optimization to experimental planning
Location: Redwood Conference Rooms C/D

  • Across the National user facilities Physicists, Chemists, Materials Scientists, Engineers and Computer Scientists are working collaboratively to adapt and develop machine learning (ML) tools to increase the efficiency of how x-rays are delivered and how science is performed at user facilities.  We propose to bring together researchers who are developing ML tools for delivering x-rays, building data analysis tools, and building artificial intelligence to design experiments.  The workshop will be designed to increase visibility and collaboration between researchers across these seemingly disparate topic areas.  Additionally, the workshop will have a secondary focus to introduce users to existing ML tools which have been developed to increase their efficiency at the user facilities, but for which they may not be aware exist.  This workshop would be followed by a broader 2-day workshop being planned in conjunction with Stanford to broadly explore how machine learning can be used to accelerate material science, with hands on demonstrations of how we can use existing data to build predictive models for future experiments.

Tips to Communicate your Science
Location: Panofsky Auditorium

  • This workshop will provide practical tips and interactive training to help scientists/users develop skills to better communicate their science to mainstream audiences, such as the general public and media, as well as elected officials and funding agencies. This session will highlight:
    • The importance of sharing your science with non-scientific audiences
    • How to communicate with government agencies and funding agencies
    • How to talk about science with the general public (e.g. public lectures, tours)
    • What makes a good story for science journalists
    • How to work with your organization’s communications office
    • Crafting your science pitch

Ultrafast Electron Diffraction (UED)
Location: Redwood Conference Room A/B

  • Responding to the recommendations of DOE BES Future Electron Scattering and diffraction workshop, SLAC has commissioned an Ultrafast Electron Diffraction (UED) R&D platform which provides MeV-, 100-femtosecond-scale electron pulses to support ultrafast science programs. This workshop is aimed at and future users interested in experiments at SLAC's MeV-UED facility. In a series of plenary talks, we will give an introduction into current and future capabilities of the UED facility, and discuss future scientific opportunities. Recent achievements from gas phase, warm dense matter and solid state experiments will also be presented . The plenary session is followed by a number of parallel breakout sessions focusing on future research ideas in AMO science, ultrafast photochemistry, time-dependent phenomena in solid samples, and investigations into warm dense matter. For these breakout sessions, we invite participants to prepare 5-minute-long presentations on their experimental ideas. To present your experimental ideas, email to workshop organizers.
