Description

SMIS is one of the two infrared beamlines at SOLEIL together with AILES. SMIS is aiming to deliver an infrared beam of high brilliance in the 1-100 microns spectral range, with a spectral region optimised for investigation between 2.5-100 microns. This synchrotron source will be coupled to an infrared microscope. The beamline is dedicated to microscopic analysis of a variety of samples, spanning from polymer films and multilayers, mineral inclusions, biological and biomedical studies, to Archaeology .An ensemble of experimental cells will be provided and adapted to accommodate various needs, and will allow, among others, to perform experiments at various temperature and pressure conditions , under mechanical actions ( stretching..)etc..
