ALBA synchrotron

ALBA (meaning "Sunrise" in Catalan and in Spanish) is a 3rd generation synchrotron radiation facility located in the Barcelona Synchrotron Park in Cerdanyola del Vallès near Barcelona, in Catalonia (Spain). It is constructed and operated by the CELLS (Consortium for the Exploitation of the Synchrotron Light Laboratory) consortium, and co-financed by the regional Catalan Government and Spanish central administration Government[1][2]

After nearly ten years of planning and design work by the Spanish scientific community, the project was approved in 2002 by the Spanish and the Catalan governments. After scientific workshops and meetings with prospective users, the facility was redesigned in 2004, and in 2006 construction started. The laboratory was officially opened for experiments on 7 beamlines in March 2010.

Beamlines[edit]

BL01 - MIRAS[3][edit]

MIRAS is for Fourier Transform Infrared (FTIR) spectroscopy and microscopy. FTIR is an potential instrument to recognize the vibrational signatures and in this manner the compound arrangement of materials.

The beamline gives ALBA users a modern synchrotron-based infrared spectrometer and microscope capacity covering a wavelength range from around 1 µm to ∼100 µm with an spectral region designed at first for investigation between 2.5-14 µm.

Transmission, Reflection, Attenuated total reflection (ATR) and Grazing incidence are the most important geometries for sample analysis, and are all available at this beamline.

BL04 - MSPD[4][edit]

The Materials Science and Powder Diffraction Beamline is for high-resolution powder diffraction and high pressure powder diffraction using diamond anvil cells.

The beamline works between 8 and 50 keV. This energy range adequately covers the desirable range for almost any powder diffraction experiment, and at the same time it is possible to perform both total scattering experiments, and high pressure diffraction, for which it is not only desirable but sometimes necessary to have high-energy sources (E>30 KeV).

There are two experimental end stations to accommodate the different experimental techniques, one devoted to high resolution powder diffraction and the second one is dedicated to high pressure experiments.

BL09 - MISTRAL[edit]

"The full-field Transmission X-ray Microscopy beamline MISTRAL is devoted to cryo nano-tomography in the water window and multi-keV spectral regions (E = 270eV – 2600eV) for biological applications. In addition, spectroscopic imaging (a series of 2D images over a range of X-ray wavelengths) at several interesting X-ray absorption edges can be performed.

The Transmission X-ray Microscope (TXM) works from 270 eV to 1200 eV. A single-reflection elliptical glass capillary condenser focuses monochromatic light on to the sample, which is at cryo-temperature. The transmitted signal is collected by an objective Fresnel Zone plate (of 25 or 40 nm outermost zone widths) and a magnified image is delivered to a direct illumination CCD camera. The routinely expected spatial resolution in 2D is 30 nm and ~50 nm for tomographies. An upgrade of the microscope to higher energies (i.e. Zernike phase contrast at 2600 eV) is planned, as well as the development of correlated fluorescence visible light microscopy.

Facilities for sample cryo-preparation as well as software reconstruction and analysis are available for the users."[5]
