Compact IR synchrotron beamline design.

Area of Science:

• Synchrotron Radiation and Particle Accelerators
• Infrared Spectroscopy and Optics

Background:

• Third-generation storage rings utilize multi-bend achromat (MBA) lattices for reduced electron beam emittance.
• The compact nature of MBA lattices severely restricts space for traditional infrared (IR) extraction beamlines.

Purpose of the Study:

• To propose and analyze an optimized optical layout for IR beamlines within confined spaces.
• To enable intense, aberration-free IR beams (1-30 µm) in space-restricted multi-bend achromat storage rings.

Main Methods:

• Design of an optical layout integrated directly inside a SOLEIL synchrotron dipole chamber.
• Analysis of the optical performance delivering near- to mid-IR beams.
• Consideration of mechanical assembly, stability, and thermo-mechanical deformation of optics within the chamber.

Main Results:

• Demonstration of an optimized optical design for IR beam extraction within a dipole chamber.
• Prediction of intense and nearly aberration-free IR beams suitable for advanced applications.
• Feasibility analysis highlighting the importance of mechanical and thermal control of integrated optics.

Conclusions:

• Dipole chambers can be adapted to provide high-quality IR synchrotron sources in compact MBA rings.
• Development of expertise in mechanical assembly and stability control is crucial for this integration.
• This approach overcomes space limitations, paving the way for enhanced IR capabilities in next-generation storage rings.
