TRISS - Trapped Ion Spectrometer Setup

We propose the realization of a suite of cutting-edge scientific instruments that will form part of an internationally unique and competitive instrumentation infrastructure at MAX IV.

The proposed project will not only enable high-impact scientific research across a number of scientific fields, but it will also nurture international collaboration and knowledge exchange, thereby contributing to Sweden’s scientific competence development.MAX IV Laboratory, hosted by Lund University, is a Swedish national laboratory that provides x-ray radiation for research across a broad range of research fields from life science and chemistry, to physics, materials science and even cultural heritage.

The proposed functional package will facilitate a range of experiments on gas-phase ionic samples, enabling research projects with significant societal relevance – industry (enhanced knowledge about nanoparticles/clusters can help to develop novel heterogeneous- and photo- catalysts) and Horizon2020 Grand Challenges – environment (atmospheric chemistry) and health (biomolecule studies).Ionic matter is the most common form of visible matter in the universe.

Important atmospheric processes are initiated by small ionic species, and interstellar reactions are modeled on chemical systems and intermediates produced in photoionization of exotic species under low-density conditions. Ions are also abundant in biological systems. However, a fundamental understanding of the mechanisms behind radiation therapy on biological systems is lacking.

These questions can be addressed by spectroscopy on trapped ions as the experimentally challenging issue of low target density can be overcome using an ion trap.

Therefore, various systems that are not easily accessible can be studied e.g., molecular ions, biomolecules, nanoscale clusters and radicals.
