Description
The upgrade of the Superconducting Cyclotron at INFN Laboratori Nazionali del Sud in Catania is aimed at improving its performance in terms of intensity of light ions, as well as in terms of reliability. In the framework of the upgrade, a key milestone has been the magnetic field measurements of the new superconducting magnet, with the following goals: a) to implement a measurement procedure able to quantify and correct errors due to coils misalignment; b) to validate the field quality in the symmetry plane evaluating the differences between the measured and theoretical values.
The measurement procedure started in February 2023 at ASG Superconductors company. The first measurement campaign was performed with coils at room temperature: it was necessary to align them with respect to the ideal symmetry plane minimizing the undesired field harmonics contents. Moreover a post-processing tool has been developed to obtain the best coils centering. The second phase has been performed considering the same measurements set with the coils operating inside the cryostat filled with liquid helium at 4.2 K. The magnetic measurements mapping data are here presented.
