    Study Notes

    Synchrotron Radiation: Introduction

    • Synchrotron radiation is electromagnetic radiation produced when charged particles (electrons) are radially accelerated by magnetic fields.
    • Magnet configurations include bending magnets, undulators, and wigglers.

    SOLEIL Synchrotron

    • SOLEIL is a particle accelerator that generates synchrotron radiation.
    • It's funded by CNRS (French National Centre for Scientific Research) and CEA (French Alternative Energies and Atomic Energy Commission).
    • SOLEIL has 43 beamlines, offering various techniques like µXRF, XPCT, and µFTIR.
    • Collaborations exist with institutions like CRNL (Centre de Recherche en Neurosciences de Lyon) and STROBE (Synchrotron Radiation for Biomedicine). Research includes studies on amyloid-beta plaques and HgTe nanocrystals.
    • Further collaborations involve Sorbonne University, an SME (small and medium-sized enterprise) called New Imaging Technologies, South Korea’s GIST and KAIST, and LCPMR (Sorbonne Université), researching topics such as ultrafine stepped Cu surface reactions with CO2 and employing NAP-XPS.

    Properties of Synchrotron Radiation

    • High intensity (increases by a factor of 1000 every 10 years).
    • Continuous spectrum.
    • Excellent collimation.
    • Polarization.

    Synchrotron Sources (3rd Generation)

    • A table lists various 3rd generation synchrotron facilities worldwide, including their location, energy (GeV), circumference (m), and year of commissioning. Examples include ESRF (France), ALS (USA), TLS (Taiwan), and many others.

    Electromagnetic Spectrum

    • Synchrotron radiation covers a wide range of the electromagnetic spectrum.

    Antarès Experimental Techniques

    • Antarès utilizes Scienta and Bruker detectors for photoemission and X-ray absorption experiments.
    • Techniques used include photoelectron diffraction, scanning imaging (with 50 nm step), nano-ARPES, nano-PhD, and nano-XAS. These leverage interference phenomena from single and double scattering events.
    • A study on graphene growth using molecular beam epitaxy on SiC is highlighted, a publication from IEMN (Lille), SOLEIL (Antarès), and LCPM (Université Pierre et Marie Curie – Paris).

    Data Acquisition System

    • Antarès features an integrated data acquisition system.

    Sample Analysis & Imaging

    • Diagrams show sample scanning, and the analysis of core levels (Si 2p, Ag 3d) using Scienta detectors, illustrating the x and y axis in nanometers.
