未来e+ e-香料工厂：加速器挑战
Future e+ e- Flavor Factories: accelerator challenges
摘要：
B工厂（PEP-II和KEKB）的运行非常成功，都超过了设计峰值和积分亮度，并为实验提供了大量良好的数据。为了获得大约两个数量级的更大亮度，日本的Super-KEKB和欧洲的SuperB正在进行升级。非常高的光束强度、非常短的聚束长度和低的相互作用点β函数是日本设计的关键点，这对硬件组件（RF、真空）来说非常具有挑战性。另一方面，SuperB采用了一种新的碰撞方案，即大Piwinski角和“蟹腰”，这将允许达到两个数量级的亮度更大，而不增加束流和减少聚束长度。在这次演讲中，我们将回顾这两个项目的现状。
英文摘要：
Operation of the B-Factories (PEP-II and KEKB) has been very successful, both having exceeded their design peak and integrated luminosity and provided a huge amount of good data to the experiments. Proposal for upgrades, in order to achieve about two order of magnitude larger luminosity, are in progress in Japan, with Super-KEKB, and in Europe, with SuperB. Very high beam intensity, very short bunch length and low Interaction Point beta-functions are the key points of the Japanese design, very challenging for the hardware components (RF, vacuum). On the other hand SuperB exploits a new collision scheme, namely large Piwinski angle and "crab waist", which will allow to reach a luminosity two order of magnitude larger without increasing beam currents and decreasing bunch lengths. In this talk the present status of the two projects will be reviewed.
