中文摘要：

当近光速的带电粒子在磁场中转向时,沿运动轨迹的切线方向将会发出很窄的电磁辐射,这种高亮度的＂光＂称为同步辐射.同步辐射的波段范围从THz到远红外/红外,一直扩展到X射线/γ射线,其卓越的性能已经成为探索物质世界强有力的工具,在物理、化学、材料科学、生命科学、医学、纳米科技等领域获得了广泛的应用.本文就同步辐射的发光机制、特点及其应用作了简单的介绍,并结合我们课题组的两个研究实例展示了同步辐射的巨大潜力.

英文摘要：

When charged particles move at a speed relative to the light, electromagnetic wave will be radiated along the tangential direction in a narrow cone--this high brightness ＂light＂ is called synchrotron radiation. Synchrotron radiation covers a broad region of electromagnetic spectrum, from THz to FarIR/IR X-ray/7 ray. Due to its excellent characteristics, synchrotron radiation becomes one of the most powerful tools insight into matters in many dif- ferent fields, such as physics, chemistry, materials sciences, biology, medical science, nano- technology, etc. This paper briefly introduces the radiation mechanism and characteristics of synchrotron radiation sources and their applications. Based on the research works of our group, as the examples, we also demonstrate the potential power of synchrotron radiation.
