AILES Beamline

Research Contents / Beamlines / Advanced Infrared Line Exploited for Spectroscopy - AILES

The AILES Beamline is dedicated to Infrared Absorption Spectroscopy for materials and molecules. The usefull spectral range spans from the Mid- to Far Infrared (IR) or Terahertz (THz) domains, but the best performance concern the 8 to 1000 cm-1 energy range, with a maximum resolution of 0.0008 cm-1.

Research on AILES involves molecular spectroscopy and studies of optical properties of materials. The concerned scientific community spreads from physics to chemistry and biology.

A high sensitivity infrared detector for spectroscopy at SOLEIL

If the traditional domain of excellence of synchrotron radiation is that of X-rays, SOLEIL also represents a currently irreplaceable broad band source for high resolution infrared (IR) spectroscopy because of its high brilliance. Researchers from SOLEIL and other synchrotrons in the world take advantage of this property for IR absorption gas analysis. To optimize the benefits of this exceptional source, scientists of the AILES beamline and the Detectors Group at SOLEIL have developed a special device which delivers a significant increase in sensitivity –approximately one order of magnitude– compared to the existing commercial systems.
