据新华社报道，我国首台国产场发射透射电镜于20日在广州发布。这标志着我国已掌握透射电镜用的场发射电子枪等核心技术，并具备量产透射电镜整机产品的能力。该电镜将为我国在材料科学、生命科学、半导体工业等前沿科学及工业领域的高质量发展提供有力支撑。
研发团队介绍，此次推出的首款场发射透射电镜新品TH-F120,取名源自中华名山“太行”，寓意它将如太行山一样成为中国透射电镜产业的脊梁。该场发射透射电镜利用被加速到120千电子伏特的高能电子与被观测样品中的原子发生相互作用，检测透射电子携带的样品信号转化为显微放大的图像，可以用来观察材料样品中的原子排列结构、细胞组织样品的精细超微结构、病毒和生物大分子复合体的精细结构，是科学家研究微观世界的重要仪器。
IT之家从公开资料获悉，生物岛实验室(原广州再生医学与健康广东省实验室)成立于2017年12月，生物岛实验室徐涛院士、孙飞研究员联合中科院生物物理所在2016年启动透射电镜有关研究，并于2020年在生物岛实验室组建起一支体系完整的透射电镜研制工程技术团队。

Title: China’s First Domestic Field Emitted Transmission Electron Microscope Released, Providing Strong Support for High-Quality Development in Materials Science and Other Fields
Keywords: Domestic Field Emitted Transmission Electron Microscope, Materials Science, Biological Island Laboratory
According to Xinhua News Agency, China’s first domestic field emitted transmission electron microscope was released in Guangzhou on the 20th. This marks that China has mastered the core technology of field emitted electron guns used in transmission electron microscopes and has the ability to produce complete transmission electron microscope products in mass production. The microscope will provide strong support for the high-quality development of cutting-edge science and industrial fields such as materials science, life sciences, and semiconductor industry in China.
The research and development team introduced that the first field emitted transmission electron microscope新品TH-F120, named after the famous Chinese mountain Taihang, symbolizes that it will become the backbone of China’s transmission electron microscopy industry, just like Taihang Mountain. The field emitted transmission electron microscope uses high-energy electrons accelerated to 120 keV to interact with atoms in the observed sample and convert the signal carried by transmitted electrons into a magnified image, which can be used to observe the atomic arrangement structure of material samples, fine超微结构 of cell tissue samples, and fine structures of viruses and biomolecular complexes. It is an important instrument for scientists to study the microworld.
IT Home learned from public information that the Biological Island Laboratory (formerly Guangzhou Regenerative Medicine and Health Guangdong Laboratory) was established in December 2017. Academician Xu Tao of the Biological Island Laboratory and researcher Sun Fei jointly launched research on transmission electron microscopes at the Institute of Biophysics of the Chinese Academy of Sciences in 2016, and in 2020, they established a comprehensive transmission electron microscope research and development engineering team in the Biological Island Laboratory.
