Description
The goals of the cSTART storage ring at Karlsruhe Institute of Technology (KIT) are to demonstrate the storage of ultra-short electron bunches and study their non-equilibrium dynamics. Furthermore, it aims to study the application of laser-plasma accelerators (LPAs) as injectors for storage rings. To allow the direct injection of LPA bunches with comparably large energy spread, cSTART has a specifically designed flexible magnetic lattice with large momentum acceptance. The non-ramping ring will also use the existing linac-based accelerator FLUTE as injector for commissioning and experiments with controlled beam parameters.
In 2024, the collaboration between KIT, RI Research Instruments GmbH, and its subcontractors completed the Technical Design Report (TDR), followed by the Final Design Report (FDR) in spring 2026. The magnets and power supplies for the injection line (IL), which will connect FLUTE to the storgae ring, are already available in KIT’s inventory. Meanwhile, the magnets, power supplies, and vacuum chambers for the storgae ring are currently in production. This contribution provides an overview of the current status an outlines the next steps of the cSTART project.
