Objectives of the MD-GAS Action


Research Coordination:

  • Develop new common methods to prepare beams of molecular ions in well-defined, or narrow ranges of, rotational and vibrational quantum states (internally cold ions).
  • Develop new common methods to prepare isomer-selected beams of molecular ions.
  • Design new experiments that use these newly developed methods for studies at synchrotron, FEL , or ion accelerator facilities.
  • Establish a common testing ground for new instruments and methods for advanced ion-beam trapping and cooling technologies – where cooling technologies concern translational and internal ion temperatures and forms (defining the isomer and its electronic and rovibrational excitations).
  • Promote new collaborations between theoreticians and experimentalists to develop the new computational tools needed to accurately describe gas phase molecular dynamics on ultrashort and ultralong timescales.


  • Establish a European forum to develop new strategies to identify molecular systems and key processes in applied sciences where detailed information on gas phase molecular dynamics is urgently needed.
  • Coordinate efforts to develop a detailed understanding of the destruction and growth of molecules and for charge transfer at collision energies and internal temperatures relevant for astrophysics/chemistry and the atmospheric sciences.
  • Promote new collaborations among different scientific communities (astronomers, astrochemists, molecular physicists, theoretical chemists) with the aim to identify the molecules responsible for the Diffuse Interstellar Bands (DIBs).
  • Coordinate efforts to develop a molecular-level understanding of the crucial initial steps of biomolecular damage and of the mechanisms for biomolecular self-protection.
  • Publish and present Action results in high impact journals and at in-field, nearby-field, and interdisciplinary conferences. Communicate the results to the general public, policy makers, and funding agencies through various dissemination channels (newspapers, web-pages, social media).


Capacity Building:

  • Act as an interdisciplinary platform for close collaborations and knowledge exchange between researchers from fundamental chemical physics and physical chemistry (experiment and theory) and applied sciences (astrophysics/chemistry, astronomy, atmospheric science, and radiation science), and with other key stakeholders from industry (e.g. developers of detectors, fast switches, and low noise electronics).
  • Exploit this platform to identify interdisciplinary scientific goals and achieve breakthroughs that go far beyond those that could be achieved within the individual fields by themselves.
  • Complete a significant number (at least 15) STSMs per year to share interdisciplinary knowledge (instrumentation, experiments, theory, applied sciences) and to stimulate scientific breakthroughs.
  • Involve early career investigators in all activities of the Action, i.e. through young scientist forums, newsletter contributions, participation in Working Group and annual meetings, and STSMs.
  • Train early career investigators on topics relevant to the Action by organizing two Training Schools during the Action.
  • Ensure that age and geographical balance is maintained during all activities of the Action.
  • Promote gender balance throughout all Action activities to further attract and retain women in the traditionally male-dominated fields of physics and chemistry.
