Description
One of the objectives of the cSTART project (compact STorage ring for Accelerator Research and Technology) is the injection and storage of ultra‑short electron bunches into a storage ring. With a storage time of 100 ms, resulting from the 10 Hz repetition frequency, and a beam energy between 40 and 90 MeV, the beam will not reach equilibrium conditions. KIT plans injection from two sources, a laser‑plasma accelerator and the linac-based FLUTE accelerator. Precise magnet positioning will be important for keeping the intended ultra‑short bunch lengths. The initial laser‑tracker‑based alignments may not be sufficient to meet the requirements for such bunch lengths, resulting in the need for additional realignment options.
This contribution presents the first studies of methods for beam-based misalignement measurements at cSTART targeted at the possibility to physically realign the magnets for improved alignment accuracy.
