Abstract

While rare on Earth, multiply-charged ions (MCIs) are abundant species in outer space. For spacecraft outside the Earth’s atmosphere, MCIs are some of the main contributors to the failure of electronic devices. While the detrimental effects of MCIs on space electronics have been known for quite 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. The impacts of MCIs on superconducting electronics used for detection and communication in outer space are particularly unknown. Here, we aim to shed light on such interactions by examining the effect of low- to medium-dose Ar⁸⁺ irradiation on the physical characteristics (e.g., surface topography, electrical transport) of microfabricated niobium (Nb) wires.

多电荷氩离子辐照微加工铌丝

虽然多电荷离子（MCIs）在地球上十分罕见，但在外层空间却大量存在。对于地球大气层外的航天器来说，MCIs 是导致电子设备故障的主要因素之一。虽然 MCIs 对太空电子设备的有害影响早已为人所知，但其相互作用的基本物理原理（与电子自由度和晶格自由度的耦合有关）非常复杂，相对来说仍未得到探索。MCIs 对外太空用于探测和通信的超导电子设备的影响尤为未知。在这里，我们旨在通过研究中低剂量 Ar8+ 辐照对微细铌（Nb）线物理特性（如表面形貌、电传输）的影响来揭示这种相互作用。

期刊介绍： Section B of Nuclear Instruments and Methods in Physics Research covers all aspects of the interaction of energetic beams with atoms, molecules and aggregate forms of matter. This includes ion beam analysis and ion beam modification of materials as well as basic data of importance for these studies. Topics of general interest include: atomic collisions in solids, particle channelling, all aspects of collision cascades, the modification of materials by energetic beams, ion implantation, irradiation - induced changes in materials, the physics and chemistry of beam interactions and the analysis of materials by all forms of energetic radiation. Modification by ion, laser and electron beams for the study of electronic materials, metals, ceramics, insulators, polymers and other important and new materials systems are included. Related studies, such as the application of ion beam analysis to biological, archaeological and geological samples as well as applications to solve problems in planetary science are also welcome. Energetic beams of interest include atomic and molecular ions, neutrons, positrons and muons, plasmas directed at surfaces, electron and photon beams, including laser treated surfaces and studies of solids by photon radiation from rotating anodes, synchrotrons, etc. In addition, the interaction between various forms of radiation and radiation-induced deposition processes are relevant.
