Experimental X-ray Calibration User (EXCALIBUR) Facility

About EXCALIBUR

EXCALIBUR provides a simple, compact, and automated solution for x-ray metrology, making it an invaluable tool for laboratories requiring high-precision measurements. Its modular design and flexibility allow it to perform a wide range of measurements not covered by commercial instruments, from crystal calibration to filter thickness mapping and areal density measurements.

Collaborations with institutions such as Sandia National Laboratories (SNL), the Los Alamos National Lab (LANL), and Lawrence Livermore National Laboratory (LLNL) highlight EXCALIBUR’s relevance in advancing diagnostics and targets for fusion energy and astrophysical research. By enabling rapid and reliable characterization of experimental targets and x-ray optics, EXCALIBUR ensures that laboratories can achieve their scientific goals with confidence and precision.
