Head-on beam-beam compensation has been implemented in the Relativistic Heavy Ion Collider in order to increase the luminosity delivered to the experiments. We discuss the principle of combining a lattice for resonance driving term compensation and an electron lens for tune spread compensation. We describe the electron lens technology and its operational use. To date, the implemented compensation scheme approximately doubled the peak and average luminosities.
为了提高向实验提供的亮度，相对论重离子对撞机中实施了对头对头束流束流补偿。我们讨论了用于共振驱动项补偿的晶格和用于调谐扩展补偿的电子透镜相结合的原理。我们描述了电子透镜技术及其运行使用情况。迄今为止，所实施的补偿方案使亮度的峰值和平均值大约增加了一倍。
