Description
technical field [0001] The invention relates to in-situ imaging technology of synchrotron radiation and metal solidification control technology, in particular to a peripheral system suitable for in-situ observation of metal solidification under synchrotron radiation. Background technique [0002] Synchrotron radiation in-situ imaging technology has the advantages of high energy, high brightness, high resolution, and good monochromaticity. It can capture the details of dendrite growth in the process of metal solidification in a timely, accurate, and continuous manner, which is of great scientific research value. However, during the imaging process, there is strong radiation in the imaging room, and operators cannot operate at close range. There is an urgent need for a long-distance control system capable of flexible displacement, temperature control, and recording, which can greatly increase the controllability of the imaging process and metal solidification.
