Description

Cavity-based X-ray Free Electron Lasers(CBXFELs) promise to transform the field of hard X-ray science by delivering radiation with exceptional brilliance, stability,and full three-dimensional coherence. At the European XFEL, we have recently achieved lasing with multi-pass gain in a proof-of-concept CBXFEL featuring a 132.8m round-trip hard X-ray cavity using diamond crystals in Bragg reflection.
This talk will present these results, and will classify them in the context of the development of CBXFEL sources and high brighntess X-ray pulses.

Preprint marking on your proceeding paper I do not intend to submit a paper associated with this contribution.
