New operation modes are considered during the development of new synchrotron light sources. An understanding of the effects involved is inevitable for a successful operation of these schemes. At the KIT storage ring KARA (Karlsruhe Research Accelerator), new modes can be implemented and tested employing a variety of performant beam diagnostics devices. Negative momentum compaction optics at various energies have been established. Also the influence of a negative momentum compaction factor on different effects has been investigated. This contribution will show a short report on the status of the implementation of negative momentum compaction optics at KARA. Additionally, first measurements of the changes to the current-dependent bunch length will be presented.
