Description
As part of the FAIR project and within the GSI and CERN collaboration, the superferric magnet production series —key components of the Superconducting FRagment Separator (SuperFRS) under construction at FAIR, Darmstadt, Germany— are undergoing rigorous testing at CERN in a dedicated cryogenics test facility.
The tested magnets include dipoles and various types of multiplets (composed of different numbers of quadrupoles, steering dipoles, sextupoles, and octupoles, housed inside a shared vacuum vessel), which must be qualified for cryogenics, electrical and magnetic field performances. The dipoles were designed by CEA (France) and manufactured by Elytt Energy (Spain), while the multiplets are produced by ASG (Italy).
This paper outlines the updated capabilities of the test facility for large-scale magnet testing. It provides a detailed summary of the tested magnet series and configurations, highlighting key results from powering tests. Special attention is given to the analysis of the quenches that occurred during magnet testing. The strategy proposed to mitigate magnet training, therefore optimizing the testing time, including precise voltage measurements and tailored powering ramps is presented. The paper concludes with the outlook of the future tests.
