Turn-by-turn horizontal bunch size and energy spread studies at KARA — •Benjamin Kehrer1, Meghana Patil1, Miriam Brosi1, Erik Bründermann2, Stefan Funkner1, Gudrun Niehues1, Marcel Schuh2, Johannes Steinmann2, and Anke-Susanne Müller1,2 — 1LAS, KIT, Karlsruhe — 2IBPT, KIT, Karlsruhe
The energy spread is an important beam dynamics parameter. It can be derived from measurements of the horizontal bunch size. At the KIT storage ring KARA (Karlsruhe Research Accelerator) at Karlsruhe Institute of Technology (KIT) a fast-gated camera is routinely used for horizontal bunch size measurements with a single-turn resolution for a limited time span. To overcome the limits of the current camera setup in respect to time and energy resolution and time span, a high-speed line array with up to 10 Mfps, the KALYPSO system, is foreseen as a successor. The KALYPSO versions range from 256-pixel to 1024-pixel and allow unlimited turn-by-turn imaging of a single bunch at KARA. We successfully tested such a system at our visible light diagnostics beamline. In this contribution, we give a status on the FGC studies and present first test results using KALYPSO.
