Ion-ion COllisioN Electron Spectroscopy

This project proposes the development of an innovative electron spectrometer to pioneer Ion-ion COllisioN Electron Spectroscopy (ICONES). Traditionally, electron spectroscopy has provided critical insights into ion-atom/molecule collisions, offering an in-depth understanding of various quantum processes such as electron capture, ionization, and excitation. However, its application to ion-ion collisions, where both collision partners are ions, is a new frontier. This research represents a significant leap beyond the current state-of-the-art, extending the use of electron spectroscopy in ion-ion collisions. The project methodology includes simulations using SIMION, assembling a portable setup with integrated electronics and data acquisition system for independent testing, and conducting proof-of-principle tests under realistic experimental conditions. ICONES will be finally integrated in the FISIC platform, which is currently being tested at the Institute of NanoSciences of Paris (INSP), CNRS. FISIC is designed to study ion-ion collisions into the hitherto unexplored intermediate energy regime, where energy deposition reaches its maximum. By leveraging recent advancements in accelerator-based technology, this project aims to open new experimental pathways, providing benchmark data for theoretical models and significantly expanding our knowledge of the complex quantum dynamics of N-body systems, thus offering detailed insights into electron correlations, the roles of screening and anti-screening in multiple mechanisms as well as multi-electron processes. The knowledge gained from this project will have broad implications across multiple fields, including astrophysics, fusion research, and ion-beam cancer therapy. Additionally, the project’s outcomes are expected to drive technological innovation by developing new spectrometers capable of high-precision measurements under extremely low-rate conditions, thus setting new standards in atomic physics research.
