Abstract

Тема выпускной квалификационной работы: «Некоторые аспекты контроля процесса производства высокотемпературного сверхпроводящего провода 2 поколения». Данная работа посвящена разработке и апробации методов диагностики длинномерных высокотемпературных сверхпроводящих лент. В результате работы был разработан, изготовлен и испытан прототип установки бесконтактного определения однородности критического тока по длине ленты, а также разработаны методики пробоподготовки и исследования подложки и функциональных слоев ленты на атомно-силовом микроскопе. Предполагается дальнейшее комбинированное использование новой установки с разработанными методиками для анализа взаимосвязи локального изменения сверхпроводящих свойств со структурой слоев. Полученные результаты применимы в сфере прикладной высокотемпературной сверхпроводимости. Значимость работы для этой сферы заключается в оригинальном методе неразрушающего контроля неоднородности критического тока по всей протяженности ленты, дополненном углубленной диагностикой отдельных участков.

The subject of the graduate qualification work is “Some aspects of the control of the production process of high-temperature superconducting wire of the 2nd generation”. The given work is devoted to the development and testing of diagnostic methods for longlength high-temperature superconducting tapes. As a result of the work, a prototype of an installation for non-contact determination of the homogeneity of the critical current along the length of the tape was developed, manufactured and tested, and methods for sample preparation and examination of the substrate and functional layers of the tape on an atomic force microscope were developed. Further combined use of the new installation with the developed methods is expected for analyzing the relationship between local changes in superconducting properties and the layer structure. The results obtained are applicable in the field of applied high-temperature superconductivity. The significance of the work for this area lies in the original method of non-destructive testing of critical current inhomogeneity along the entire length of the tape, supplemented by in-depth diagnostics of individual sections.
