BL 09.1 - SISSI - Mat

Synchrotron Infrared Source for Spectroscopy and Imaging - Materials Science branchline (SISSI-MAT)

The SISSI infrared beamline at Elettra extracts the IR and visible components of synchrotron emission for performing spectroscopy, microspectroscopy and imaging. The applications cover a wide range of research fields, including surface and material science, biochemistry, forensics, microanalysis, geosciences, cell biology, biomedical diagnostics, microfluidics, high-pressures, time resolved IR, conservation science, protein folding, chemical kinetics etc.

The SISSI-MAT branchline, operated by CNR-IOM, is equipped with a VERTEX 70v spectrometer coupled to a Hyperion-2000 infrared microscope for spectroscopy and spectromicroscopy measurements over a broad spectral range. In particular, the possibility to mount different detectors as well as beamsplitters allows exploiting a diffraction limited beam from the visible down to the terahertz. The branchline is also equipped with a cryostat and a diamond anvil cell, thus permitting to explore the behavior of matter at extreme conditions of temperature and pressure.

Endstations or Setup

SISSI-MAT

Description
SISSI-MAT branchline of SISSI beamline allows investigation of matter from far infrared to visible. The beamline is equipped with a Vertex 70v Michelson interferometer coupled to a Hyperion 2000 IR microscope. Measurements can be performed in sample compartment and under the microscope, both in reflection and transmission modes. Several sample holders are available. SISSI-MAT is also equipped with a He-N2 cryostat for low temperature studies, as well as a symmetric diamond anvil cell (DAC) for studies of matter under extreme conditions. Users can bring their additional equipment (e.g., resistive heating system, their own DACs, etc...).
