Description
ALBA synchrotron light source (www.cells.es) is the largest Spanish research infrastructure that started full operation of its first seven beamlines on February 2013. Nowadays, there are eight beamlines in operation and three under construction.
I will divide the talk in three parts: i) a very brief general description of ALBA synchrotron and the Experiments Division that it runs the user program; ii) an overview of the eight operating beamlines and some recent scientific highlights arising from their usage; and iii) a summary of the three beamlines under construction and those approved but still not funded.
Firstly, I will start with a very brief description ALBA synchrotron including our structure to fulfil our mission as user-oriented Large Facility. Then, the structure of the Experiments Division which is optimised for running our external user program: both academic and industrial usage, will be discussed. This structure, with six sections, includes the user office (our interface with the users).
Secondly, I will introduce our eight operating beamlines. I will give some technical details as well as recent scientific highlights. The beamlines within the Chemistry & Material Science Section are: 1) high-resolution and microdiffraction powder diffraction (BL04-MSPD) which has two endstations, one devoted to very high resolution and very fast powder diffraction and another to microdiffraction running a high-pressure program; and 2) X-ray absorption (XAS) and emission (XES) spectroscopies (BL22-CLAESS) which has also two endstations, one for XAS (both transmission and fluorescence) and a second for XES. The beamlines within the Electronic & Magnetic Structure of Matter Section are: 3) photoemission spectroscopy (BL24-CIRCE) which has two endstations, one devoted to near ambient pressure photoemission (NAPP) and another to photoelectron emission microscopy (PEEM); and 4) soft X-ray Magnetic Circular/Linear Dichroism Absorption and Scattering (BL29-BOREAS) which has two endstations, one devoted to absorption spectroscopy and another to scattering. The beamlines within the Life Science & Soft Condensed Matter Section are: 5) macromolecular crystallography (BL13-XALOC), 6) soft X-ray full-field cryo-tomography (BL09-MISTRAL); 7) small angle and wide angel X-ray scattering (BL11-NCD) with two endstations for SAXS and WAXS; and 8) infrared microspectroscopy (BL01-MIRAS).
Thirdly, I will describe the three additional beamlines which are being currently built: 9) angle resolved photoemission spectroscopy BL (BL20-LOREA) that it will become operational in March 2019; the absorption / powder diffraction / metrology and development BL (NOTOS) which it comes to operation in April-2020, and 10) microfocus for macromolecular crystallography BL (BL06-XAIRA) which it is expected to become operational in late 2020. Some details about the additional ALBA phase-III beamlines will be provided.
