Next-Generation X-Ray Laser Light Sources

Objective

X-ray free-electron lasers (XFELs) are today’s by far most advanced technology for imaging of atomic structures and ultrafast dynamics, underpinning breakthroughs in life sciences, structural biology, materials, semiconductor and fusion science and technology. However, today’s XFELs rely on kilometre-scale underground electron accelerators housed in billion-euro facilities, restricting them to a handful of large giga-infrastructures worldwide. As a result, research teams that want to use XFELs need to go through long application processes and even if successful face year-long waiting times for very limited one-time access to these systems. Access to XFELs today thus represents a severe bottleneck to faster and more efficient scientific and technological progress.

NEXLIGHT aims to lay the groundwork for creating an industry that builds transformative next generation XFELs which are >100x smaller than today’s XFELs (~10 meters instead of several kilometres), >100x less costly (<€20m instead of >€bn), and which can facilitate experiments which are scientifically impossible at today’s XFELs. Access to XFEL beamtime would become widely available, either through the establishment of regional XFEL centres where customers can flexibly book low-cost beamtime, or by stakeholders outright purchasing dedicated XFELs for their own exclusive use. This transformation would make XFELs a) routine instruments for scientific research, allowing new insights to be achieved faster and at lower costs, and b) a key enabling technology for high-value industrial applications, including semiconductor manufacturing, pharmaceutical drug discovery, and dvanced energy technologies.

NEXLIGHT’s XFEL systems will be based on the combination of two break-through technological concepts: a) plasma wakefield acceleration, which provides accelerating gradients orders of magnitude higher than conventional technology, and b) electron beams from plasma photocathodes, which have been developed during the NeXource ERC project and are many orders of magnitude brighter than traditional electron beam sources.
