Preserving 3D beam information in one streak camera measurement* — •Michael Switka and Wolfgang Hillert — Elektronen-Stretcher-Anlage ELSA, Physikalisches Institut, Universität Bonn

At the pulse stretcher ring ELSA, the imaging of fast beam dynamics is performed by a streak camera system. The design of its optical beamline has been optimized to match the machine characteristics and allows simultaneous observation of all three beam dimensions at various time scales down to the picosecond regime. The streak camera naturally displays longitudinal information at the expense of one transverse dimension. Hence, in order to preserve 3D beam dynamics in one single shot measurement, the beamline couples two images onto the streak camera slit of which one is perpendicularly orientated to its double. This technique is used in slow sweep and synchroscan camera operation. Characteristics and exemplary measurements, demonstrating the capabilities and limits of this technique, are presented. *Work funded by the DFG within SFB TRR16
