Description

LCLS is currently developing and deploying beamline optimization techniques at their x-ray endstations. This is an increasingly important topic at LCLS as it fully leverages its new high rep-rate superconducting beam. The increased throughput of the LCLS-II era suddenly shifts the performance bottleneck to on-shift beam setup time. As part of the Illumine collaboration, LCLS is leveraging bayesian optimization techniques with on-the-fly machine learning in conjunction with more conventional iterative alignment and digital twin techniques to automatically optimize the beam quality and streamline common elements of experiment startup setup. This talk will go over how it works, what worked well, challenges faced, and more from a controls perspective.
