Bio and material applications

Laser-driven secondary sources at ELI-Beamlines will be used for applications in molecular, biomedical, and materials (MBM) sciences. Planned applications include coherent diffractive imaging, atomic, molecular, and optical (AMO) sciences, soft X-ray materials science, hard X-ray scattering, diffraction, spectroscopy and imaging, advanced optical spectroscopic techniques, and pulse radiolysis.

Bio and material applications

The research group for applications in molecular, biomedical, and materials (MBM) sciences develops and runs experimental stations using the secondary sources that are driven by the uniquely powerful ELI-Beamlines lasers as well as the lasers themselves. The MBM group mainly develops scientific end stations for time-resolved photon science applications in the THz-to-hard X-ray range with a focus on dynamics in the femtosecond-to-microsecond time scales. These stations are:

  • A multi-purpose end station for atomic, molecular, and optical (AMO) sciences and coherent diffractive imaging (CDI)
  • A materials science platform based on a time-resolved spectroscopic ellipsometry in the optical range and VUV magneto-optical ellipsometry
  • A modular station for hard X-ray sciences covering applications in diffraction, spectroscopy, pulse radiolysis and imaging
  • Advanced optical spectroscopy capabilities in the THz-to-UV range, including a setup for stimulated Raman scattering, transient optical absorption, IR (1D and 2D) and pulse-shaping and coherent control.

Already in 2018, the MBM team provided more than 1 200 hours of experimental time for external collaborators. In February 2019, we published our first open call for users to participate in user-assisted commissioning and early experiments resulting in the scheduling of about 20 experiments during the period June to September.

Together with our close collaborators in the ELIBIO team, we make up a highly international team consisting of 15 nationalities working at the ELI Beamlines facility.
