Description

The investigation of deuterium retention under normal operation ITER regime and disruption were performed by means of exposition of RGT graphite samples in stationary deuterium plasma and subsequent irradiation by power pulse deuterium plasma imitating disruption. The deuterium distribution in the irradiated RGT graphite was determined by the nuclei recoil technique. An analysis of the distribution confirms the diffusion of deuterium deep into the targets

Abstract (Russian)

Исследованы профили распределения дейтерия в образцах графита марки РГТ после длительного облучения стационарной и затем мощной импульсной дейтериевой плазмой, имитирующей срывы плазмы в термоядерном реакторе. Распределения дейтерия определены методом регистрации ядер отдачи. Анализ кривых распределений свидетельствует о диффузии дейтерия на большие глубины
