ALBA
BL01 (MIRAS)

The infrared microspectroscopy beamline (MIRAS), dedicated to infrared microspectroscopy, is a valuable tool to identify the chemical composition of materials at the molecular level. The aim of this beamline is to allow infrared microspectroscopy and imaging, using a Fourier Transform interferometer with capacity to address the present and the future requirements of the scientific community. The scientific applications of MIRAS is covering a wide range of research fields, including surface and material science, biochemistry, microanalysis, archaeology, geology, cell biology, biomedical diagnostics, environmental science, etc.

MIRAS is dedicated to infrared microspectroscopy, with the aim to deliver world class performance in terms of a bright and highly stable photon beam. The beamline will provide ALBA users with a modern infrared microspectroscopy facility covering a wavelength range from 0.4 to 100 µm with a spectral region optimized for investigation between 2.5-14 µm. The design of the beamline optimizes performance in the mid-IR range and will give significantly enhanced efficiency, compared to a conventional source, in both far-IR and mid-IR regions.

Detectors

50 µm HgCdTe (MCT) Detector (10000-600 cm-1)

Type
Photodetector
Description
The detector is based on liquid nitrogen cooled Mercury Cadmium telluride (MCT) detector, which are sensitive from approximately 10000 to 650 cm-1. Such a detector is a photoconductive one that depends on the quantum nature of radiation. It is a ternary semiconductor compound which exhibits a wavelength cut-off proportional to the alloy composition. The long wavelength cut-off for this ternary alloy system is usually set to 650 cm-1
