Abstract

Magnetic field errors and misalignments of magnetic and diagnostic components induce spurious emittance growth. The aim of this study is to correct the impact of such errors on the ELI-NP Gamma Beam System low energy line for an effective commissioning of the machine. To perform this study we use the simulation code elegant, for alignment and trajectory stabilization methods such as one-to-one steering, fast-trajectory-feedback (FTF) or global method and Dispersion Free Steering (DFS). We show the latter to be the most robust trajectory control method for magnetic elements and monitor errors.
