Soft x-ray instrumentation and its applications at the advanced photon source

Area of Science:

• X-ray Science
• Materials Science
• Spectroscopy

Background:

• The intermediate x-ray energy range (0.5-4 keV) is underexplored.
• This region is vital for microelectronic, biological, and materials science applications.
• Key atomic transitions (rare-earth 3d-4f, K-shells) occur here.

Purpose of the Study:

• To address the underdeveloped knowledge in the 0.5-4 keV x-ray range.
• To support advanced microscopy and magnetic circular dichroism experiments.
• To facilitate research in microelectronics, biology, and materials science.

Main Methods:

• Design of two new beamlines at the Advanced Photon Source (APS).
• Utilizing an undulator source for enhanced photon flux.
• Detailed description of beamline layout and proposed experimental programs.

Main Results:

• The new beamlines are specifically designed to cover the 0.5-4 keV energy range.
• The undulator source provides necessary intensity for experiments.
• The beamline designs accommodate a range of scientific investigations.

Conclusions:

• The developed beamlines will significantly advance research capabilities in the intermediate x-ray energy range.
• These facilities will enable novel experiments in magnetism, materials science, and beyond.
• The APS is poised to become a leading center for 0.5-4 keV x-ray research.
