Description

Increasing the number of X-ray free electron laser (XFEL) facilities and capabilities across the United States is critical to keep pace with the growing demand from the user community. We are exploring a novel concept based on two-beam acceleration technology, with a focus on delivering coherent X-ray pulses with agile and customizable properties. The Coherent Agile Pulse at Argonne X-ray Source (CAPAX) platform leverages ANL's expertise in high-gradent acceleration, bright electron source, and undulator design to enable rapid reconfiguration of key pulse parameters. This paper discusses the overall architecture of the proposed concept, its key technological building blocks, and its expected photon beam performance, with the goal of establishing CAPAX as a new paradigm for flexible, user-driven XFEL science in the US.
