Abstract

Представлены экспериментальные исследования 4-проволочных Х-пинчей на модернизированном генераторе КИНГ, состоящем из четырех низкоиндуктивных конденсаторов, с максимумом тока 160–250 кА, временем нарастания тока 150–300 нс при зарядном напряжении 45 кВ. Продемонстрирована возможность использования генератора в качестве источника мягкого рентгеновского излучения при использовании стандартных Х-пинчей проволочек из Al, Cu или Mo диаметром 25 мкм. Показано, что модернизация привела к увеличению индуктивности, но не к ухудшению параметров Х-пинча. Это привело к возможности применения данного генератора для питания стандартных Х-пинчей и их использования в качестве источников излучения для точечной проекционной радиографии с пространственным разрешением порядка 13–23 мкм.
