A Single-event Analysis System for Multiply-Charged Ion Interaction Physics
Abstract
Multicharged ions (MCIs) can be found in solar flares and the solar wind as well as in the ablation zones of laser-solid impacts. For spacecraft outside the earth s atmosphere, MCIs are some of the main contributors to the failure of electronic logic and sensing devices. For laser-impacted solids, they are a primary means of energy dissipation and damage. While the generic detrimental effects of MCIs have been known for some time, the underlying physics of their interactions, which are tied to the coupling of both electronic and lattice degrees of freedom, are complex and remain relatively unexplored. In this project, we propose to acquire the necessary tools to construct a state-of-the-art Single-event Analysis System (SAS) to study the interaction between MCI at the single ion limit with superconducting nanostructures and nano-devices. The proposed SAS apparatus will be equipped with a full suite of high-resolution high-sensitivity radiation and particle detectors for recording the MCI-superconductor interaction in situ. This includes high-resolution single-photon detectors, position-sensitive detectors, secondary electron, Auger detectors as well as CCD cameras. The samples in the SAS will be mounted on a cryocooler (T less than 2.7 K) with a broad range of in-situ position and angle change capabilities. The SAS apparatus will be instrumental in shedding light on the unknown mechanisms of MCIs as they scatter, deexcite, and couple electronically to solid targets, particularly superconductors. The SAS data will be critical in the future development of highly-efficient on-chip MCI detectors that can help better evaluate the characteristics and population distribution of ionic compounds present in space weather.
