Description

With the VSR upgrade for the BESSY II electron-storage ring bunch resolved diagnostics are required for machine commissioning and to ensure the long-term quality and stability of operation. For bunch-length measurements a dedicated beamline equipped with a fast streak camera was set up and successfully commissioned. The beamline is also capable of direct beam-profile imaging and interferometry of the vertical beam size using the X-ray blocker bar. Optimisations are still ongoing. 2D bunch-resolved measurements with an additional transverse dimension are already possible with the streak camera. First results of 2D bunch-resolved measurements on the “pulse picking by resonant excitation” (PPRE) bunch are presented.
