S01.00001: End to End with Lasers: Today's growing XFEL Landscape Invited Speaker: Marc Guetg X-ray Free Electron Lasers have revolutionized the field of photon science. The first facility going online twelve years ago, LCLS, was already outshining storage rings by several orders of magnitude in terms of peak brilliance. Meanwhile there are several more facilities worldwide in an ever-growing collaboration to further the field. There is a constant push to stretch the envelope of the operational ranges of photon beam properties like wavelength, pulse length, power, polarization and coherence to name a few. This talk will present an overview of current XFEL facilities and their capabilities, introduce the working principle of various operation modes enabling those achievements and explore some future setups envisioned to open the door for new scientific opportunities.

S01.00002: Lasers for Plasma Accelerators Invited Speaker: Carl Schroeder Laser-driven plasma-based accelerators are capable of generating ultra-high accelerating gradients, several orders of magnitude larger than conventional accelerators. These high gradients offer the potential for extremely compact devices delivering high energy particle beams. In a laser-plasma accelerator, ultra-short, intense lasers drive relativistic plasma waves that accelerate charged particle beams. In this talk, I will describe recent experimental progress on laser-plasma accelerators. Applications of these accelerators are limited by laser technology, and, in particular, the availability of high peak and high average power, short-pulse lasers. Today's laser-plasma accelerator experiments use Ti:sapphire lasers, which are presently limited to a few Hz repetition rates. Recent technology advances have made kHz repetition rates possible. Beyond kHz, new laser technologies must be employed. Coherent combining of fiber lasers offer the possibility to achieve high average and high peak power lasers suitable for high-energy physics applications. I will describe the recent progress in coherent combining of fiber lasers as well as other possible laser technology options, such as TmYLF, to achieve high average power laser-plasma accelerators.

S01.00003: Machine Learning Applications in Accelerator Science Invited Speaker: Daniel Ratner In the last decade, machine learning (ML) techniques have surged in popularity across all areas of science, and accelerators are no exception. With a wealth of data, extensive automation, and daunting operational requirements, particle accelerators are ideal targets for machine learning. While ML may be best known for applications in data analysis, there are additional opportunities across autonomous control, surrogate modeling, and fault detection/recovery. In this talk I will give examples of ML applications at SLAC’s accelerator facilities in each of these areas, as well as a vision for the role of ML in the design and operation of future accelerators.
