Validation of the Vertical Corrector Magnets for HESR Using COMSOL Modeling and Python Data Analysis

In this paper we report on the validation of the series-produced vertcal corrector magnets designed for the High- Energy Storage Ring (HESR) within the FAIR project [1]. While the companion study [2] details the measurement system and Hall probe campaign, the present work focuses on processing the experimental datasets and their systematic comparison with numerical simulations. Using the Python programming language and its scientific libraries, the main magnetic characteristics were derived and analyzed: the local excitation curve (f1), the integral excitation curve (f2), the effective magnetic length (f3), and the local homogeneity curve (f4),[3]. The magnetic field distribution of the corrector magnet was simulated with COMSOL Multiphysics, which served as a consistent theoretical framework for comparison with the measurements.
