摘要

本文介绍了第二代高温超导线材样品在室温下受能量为 670 MeV、通量为 1011 和 1012 cm-2 的铋离子辐照后的磁化、动态磁感应强度和微观结构的研究结果。研究确定了超导转变温度和临界电流密度与通量的关系。对于辐照到 1011 cm-2 的样品，与未辐照的对照样品相比，临界电流密度有所增加。辐照样品的微观结构分析表明存在非晶轨道，可作为有效的引脚中心。

Superconducting Properties of 2G HTS Wires Irradiated by Bi Ions with Energy 670 MeV

The investigation results of magnetization, dynamic magnetic susceptibility and microstructure of samples of second generation high-temperature superconducting wires irradiated by Bi ions at room temperature with energy of 670 MeV and fluences of 10¹¹ and 10¹² cm^–2 are presented. The dependences of the superconducting transition temperature and critical current density on the fluence have been determined. For the sample irradiated to fluence 10¹¹ cm^–2, an increase in the critical current density is observed compared to the control nonirradiated sample. The microstructure analysis of irradiated samples demonstrates the presence of amorphous tracks, which can act as effective pinning centers.
