The upgrade of the BESSY II light source in Berlin towards a variable pulse-length storage-ring will lead to a complex bunch-filling pattern. This may involve co-existing electron bunches with significant variations of their properties. Among many other conditions, it calls for bunch-resolved diagnostics with sub-ps time resolution and micrometer spatial resolution. Currently, we are finishing the constructing of a diagnostic platform connected to new dipole beamlines for visible light as well as THz measurements. The mid-term aim is 24/7 use of optical beam diagnostics and the development of advanced methods for specific purposes. Preliminary interferometric data for transverse beam profiles are presented and discussed. The main topic of this paper, however, are recent streak-camera results along with concepts to achieve high signal-to-noise ratio, high time resolution and 2D diagnostics at high efficiency.

柏林的BESSY II光源升级为可变的脉冲长度存储环将导致复杂的束填充模式。这可能涉及电子束的共存，其电子束的性能有很大变化。在许多其他情况下，它要求以亚ps时间分辨率和千分尺空间分辨率进行束解析诊断。目前，我们正在完成诊断平台的构建，该诊断平台连接到新的偶极子束线，用于可见光和THz测量。中期目标是24/7全天候使用光束诊断和开发针对特定目的的先进方法。提出并讨论了横光束轮廓的初步干涉数据。但是，本文的主要主题是
