Action spectroscopy is a key method for the structural characterization of ionized species. When a tunable source like the infrared free-electron laser (CLIO) is used, this technique provides detailed information about the structure of ions. Over the years, this methodology has been refined by coupling IR and UV lasers with both high and low mass-resolution ion traps (FTICR and Paul Trap), offering a powerful tool that is uniquely accessible worldwide in Orsay (CLIO) or Nijmegen (FELIX).<\/p>\n

The SMAS\/CLIO platform has been a user facility within the CNRS Research Infrastructure Infranalytics<\/a> since January 2022, and it joined the Operando-Prototyping platform of the PEPR LUMA<\/a> \u00a0in January 2024.<\/p>\n

A new klystron was acquired in 2022 and delivered in 2023. Its installation was completed in July 2024. The restart of the free-electron laser is underway, and user operations are expected to resume in January 2025.<\/p>\n<\/div>\n<\/div><\/div><\/div>

The team has developed particular expertise in the spectroscopic characterization of post-transcriptional modifications, in collaboration with Professor M.-E. Crestoni\u2019s group in Rome. This collaboration has led to significant advances in the study of biological molecules and drugs used in cancer treatments, such as Cisplatin.<\/p>\n

The group has conducted notable research on various topics, including:<\/p>\n
