Description

In order to achieve optimal performance in terms of transmission and separation for the S3 spectrometer, the project chose to design superconducting magnets integrating 11 magnetic functions in a single cryostat. There are seven of these magnets, called Superconducting Multipole Triplets, in the spectrometer. The compactness of these magnets makes them remarkable and unique, but has led to significant commissioning difficulties. As the design was very close to the acceptable operating limits, we experienced several breakages and leaks, as well as limitations in terms of nominal current. In this presentation, we will show the important work we carried out to repair the main conductor, improve the robustness of the current leads and feedthrough, and repair the various leaks.
