论文摘要
连贯的电子冷却是一种通过在电子束上的噪声印记，放大电子密度调制的噪声，并使用它们将冷却踢施加在Hadron上，从而使高强度强度束冷却。这些扰动的典型尺寸可以在$ $ m的比例上，这使我们能够将经典随机冷却的范围扩展到几个数量级。但是，至关重要的是要确保电子和强子梁在相同的$ $ m尺度上纵向对齐。为了提供此过程的快速反馈，我们讨论了信号抑制至相干电子冷却的扩展，并在理论和模拟中表明，强子束中光谱噪声的某些成分将在几个百分比的水平上进行预测，这可以通过黑龙光束的辐射观察到。
Coherent electron cooling is a promising technique to cool high-intensity hadron bunches by imprinting the noise in the hadron beam on a beam of electrons, amplifying the electron density modulations, and using them to apply cooling kicks to the hadrons. The typical size for these perturbations can be on the $μ$m scale, allowing us to extend the reach of classical stochastic cooling by several orders of magnitude. However, it is crucial to ensure that the electron and hadron beams are longitudinally aligned within this same $μ$m scale. In order to provide fast feedback for this process, we discuss the extension of signal suppression to coherent electron cooling, and show in both theory and simulation that certain components of the spectral noise in the hadron beam will be predictably modified at the several percent level, which may be detected by observations of the radiation of the hadron beam.
