The award is to design a compact electron storage ring with circumference about 3 m capable of producing X-rays at energy 5 to 80 KeV, by employing inverse Compton scattering of laser at 800 nm wave length with electron beams at 20-60 MeV. The photon flux is estimated to be about 100 billion photons/second. The award will evaluate effects of the collective instability, intrabeam scattering and Touschek lifetime. We will carry out experiments at the ALPHA stroage ring to characterize beam properties. In addition to the compact light source, the award will carry out design of a compact proton storage ring at energy of about 300 MeV. Such proton storage rings can provide industial and medical applications.The award is to investigate beam dynamics problems associated with high brightness low energy storage rings and its applications in the generation of inverse Compton X-ray source, and possibly coherent light sources. This award is also intended to investigate physics associated with high power accelerators. Topics associated with high power accelerators are space charge physics, synchrobetatron coupling, nonlinear beam dynamics and collective beam instabilities. The award activities also include training of future accelearator scientists.

该奖项是设计一个紧凑的电子存储环，周长约3米，能够产生能量为5至80 KeV的X射线，通过使用20-60 MeV的电子束与800 nm波长的激光的逆康普顿散射。光子通量估计约为1000亿光子/秒。 该奖项将评估集体不稳定性，束内散射和Touschek寿命的影响。我们将在阿尔法储存环上进行实验，以表征束流特性。除了紧凑型光源外，该奖项还将设计能量约为300 MeV的紧凑型质子储存环。这类质子储存环可用于工业和医学领域，该奖项旨在研究与高亮度低能储存环相关的束流动力学问题及其在产生逆康普顿X射线源和可能的相干光源中的应用。 该奖项还旨在研究与高功率加速器相关的物理学。 与高功率加速器相关的主题是空间电荷物理，同步加速器耦合，非线性束流动力学和集体束流不稳定性。 奖励活动还包括培训未来的加速器科学家。
