Ricerc@Sapienza

The laboratory is equipped with

a state of the art Quantum Cascade Laser (QCL) THz sources with emission powers in the mW range and between (1.9-5) THz;

a state of the art 2D sensor composed of microbolometers at room temperature (and other pyroelectric sensors).

a high resolution (down to 10 MHz) coherent spectroscopy system at THz frequencies composed by a combination of photoantennas and IR lasers in optical fiber.

L'attrezzatura è costituita da un modulo FT-IR di ultimissima generazione estremamente versatile che permette di investigare la ampia gamma di lunghezze da 8000 cm^-1 

La strumentazione di compone di due unità:

FTIR-microscopy is an advanced technique that couples the capability of FTIR to provide a chemical analysis of samples, with the magnification power of an IR microscope. This combination allows to add a remarkable spatial resolution (e.g. <10 or <4 microns in reflection/transmission or ATR using Ge crystals) to the infrared spectroscopic analysis of materials, thus opening the door to spatial chemical discrimination of domains in inorganic or hybrid composites as well as in bio-materials.

TeraStat2 is an HPC infrastructure developed by the Dipartimento of Scienze Statistiche and hosted by the InfoSapienza IT center of University of Rome - La Sapienza. It provides a general-purpose, massively parallel supercomputing infrastructure for solving large mathematical models on Big Data.
