The AILES beamline is conceived for absorption spectroscopy, applied to the study of molecular orsolid state systems. It covers the electromagnetic spectrum region ranging from the mid- to far infrared (IR) or THz range (4000 to 5 cm-1 ).
In addition to the increase in flux and brilliance made possible by the Synchrotron Radiation, the beamline has been designed for a high level of mechanical stability, to minimize the noise level. This was achieved using high stability optical mounts and chambers, compatible with the interferometers' optical throughput. Radiation emitted in a magnetic dipole is collected and refocused at the entrance of two Michelson-type interferometers (FTIR). These two spectroscopic workstations are, in general, dedicated to rovibrational studies of molecular systems (AILES A, with the highest resolution, 0.1μeV or about 0.001 cm-1 ) and to studies of optical properties of condensed matter (AILES B, 0.007cm-1)
The two experimental workstations are complemented by various sampling devices, enabling the different studies of matter in gaseous, liquid and solid phases. Research projects on AILES concern different applications in physics, chemistry and biology.
The aim of the beamline is to answer the needs of scientific projects for which bridging the spectral gap between conventionel IR and microwave radiation is particularly important, and combining high flux and stability over a broad band source.

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.
