Description
The upgrade project of the ALBA Synchrotron Light Source is gaining momentum following the official approval of the required funds at the end of 2025. The design of the magnets for the new ALBA II storage ring began in 2021 with the launch of a comprehensive prototyping program aimed at developing and validating the various magnet types required by the new multi-bend achromat (MBA) lattice. The first prototype magnets became available at the end of 2025 and are currently being characterized at ALBA’s magnetic measurements laboratory to assess their performance against the design specifications, as well as to investigate critical aspects such as magnetic cross-talk and mechanical integration between neighboring magnets. In parallel with prototype fabrication, the magnet designs have continued to evolve to keep pace with the successive refinements of the ALBA II lattice over the past years. The lattice is now approaching its final configuration, and together with the lessons learned from the prototyping campaign, this will enable the completion of the magnet designs during 2026. This contribution presents the current status of the magnet prototyping program and outlines the pathway toward the final magnet designs, emphasizing the main challenges encountered and the technological solutions implemented.
