标题： Synchrotron radiation of crystallized beams

摘要： 我们研究电荷在存储环中冷却时同步辐射的修改。电荷之间的对相关长度在同步辐射中表现出来，并且对于比电荷之间的相干长度更长的波长存在相干效应。因此，同步辐射可以作为诊断工具来确定存储环中带电等离子体的状态（气体、液体、晶体）。我们还表明，对于结晶束，同步辐射的总功率大大减少。这为使用小尺寸的循环加速器加速粒子到超相对论能量提供了可能性。 显示英文摘要

摘要： We study the modifications of synchrotron radiation of charges in a storage ring as they are cooled. The pair correlation lengths between the charges are manifest in the synchrotron radiation and coherence effects exist for wavelengths longer than the coherence lengths between the charges. Therefore the synchrotron radiation can be used as a diagnostic tool to determine the state (gas, liquid, crystal) of the charged plasma in the storage ring. We show also that the total power of the synchrotron radiation is enormously reduced for crystallized beams. This opens the possibility of accelerating particles to ultra-relativistic energies using small-sized cyclic accelerators.
