Optics (XSD-OPT)

The core mission of OPT is to develop and deliver innovative x-ray optics and optical systems and provide related services to further the APS mission of enabling cutting-edge scientific research. In support of this mission, the Optics group:

  • Designs, fabricates, and characterizes x-ray optical elements, such as crystal monochromators and analyzers, single- and multi-layer optics, and nanofocusing optics;
  • Operates and develops optics fabrication and characterization laboratories and instruments, including the crystal optics fabrication laboratory, the deposition laboratory, the optical metrology laboratory, and the 1-BM Optics Testing Beamline; and
  • Conducts R&D to develop future-generation optical components, such as wavefront- preserving optics and wavefront sensors and characterization tools, as well as beamline optics simulation, diagnostics, and optimization tools.

Established in the mid-1990s after the commissioning of the APS, OPT has evolved to comprise the following main activities: 1) crystal optics and multilayer optics development and fabrication, 2) zone plate development and fabrication, 3) beamline optics simulation, characterization, and optimization, 4) optical metrology, and 5) operation of the 1-BM Optics Testing Beamline.

Optical Metrology

The mission of the metrology laboratory is to evaluate optical quality of x-ray mirrors and substrates to be used in the APS beamlines, in order to ensure compliance with the user's specifications in terms of surface figure error and finish. The lab can characterize x-ray mirror-bender assemblies and specialized optics as well as carry out joint R&D programs to develop new metrology measurement techniques and instrumentation.

 

 

 
X-ray Beam Wavefront Sensors, Characterization, and Diagnostic

The optics group develops advanced wavefront sensing and coherence measurement techniques to support APS optics development and beamline characterization and diagnostic.
