Studies on Instabilities and Negative Momentum Compaction Operation at KARA — •Patrick Schreiber¹, Tobias Boltz¹, Miriam Brosi², Alexander Papash², Marcel Schuh², Bastian Haerer², Akira Mochihashi², and Anke-Susanne Müller^{1, 2} — ¹LAS, KIT, Karlsruhe — ²IBPT, KIT, Karlsruhe

New operation modes are often considered during the development of new synchrotron light sources. An nderstanding of the instabilities involved is inevitable for a successful operation of these schemes. At the Karlsruhe Research Accelerator, KARA, new modes can be implemented and tested employing a variety of performant beam diagnostics devices and therefore instabilities in those regimes can be investigated. Currently, a negative momentum compaction optics is being established. In order to reinject quickly, the operation with a negative momentum compaction factor is being implemented at injection energy (500 MeV). This contribution presents the status of the implementation of this new regime as well as first results of instability studies at this energy.
