摘要:

发展快速探测方法对电子束团进行综合监测是实现对MHz重复率储存环同步辐射综合控制的前提。在这里,我们提出了一个原理验证实验,详细描述了我们的实现,通过单发,近场电光采样在卡尔斯鲁厄研究加速器(KARA)检测纵向电子束分布。我们的实验配备了一个超快的线阵列相机提供高吞吐量的MHz数据流。我们表征所获得的数据集的统计特性,并给出了详细的描述的数据处理以及计算的电荷密度分布,其中测量的短聚束操作模式的KARA。最后,我们讨论了聚束轮廓动力学的一个著名的同步振荡的例子上的粗粒度的水平上的属性。

英文摘要:

The development of fast detection methods for comprehensive monitoring of electron bunches is a prerequisite to gain comprehensive control over the synchrontron emission in storage rings with their MHz repetition rate. Here, we present a proof-of-principle experiment with at detailed description of our implementation to detect the longitudinal electron bunch profiles via single-shot, near-field electro-optical sampling at the Karlsruhe Research Accelerator (KARA). Our experiment is equipped with an ultra-fast line array camera providing a high-throughput MHz data stream. We characterize statistical properties of the obtained data set and give a detailed description for the data processing as well as for the calculation of the charge density profiles, which where measured in the short-bunch operation mode of KARA. Finally, we discuss properties of the bunch profile dynamics on a coarse-grained level on the example of the well-known synchrotron oscillation.
