TL;DR: In this article, the critical current of Nb3Sn superconducting bending magnets was characterized at 4.3 K in the FRESCA cable test station, and a comprehensive post analysis consisting of non-destructive micro-tomography followed by microscopic characterization of metallographic cable cross sections was carried out after a critical current test to reveal cracks in the sub-elements of the loaded specimen.

TL;DR: In this article, the authors measured Young's moduli of typically used polymers during in situ heat cycles with the dynamic resonance method and compared the results with the results obtained from quasi-static stress-strain measurements at room temperature, 77 K and 4.2 K.

TL;DR: In this paper, the design of reinforced electrical insulation of the dipole cold diodes and the associated project organization are presented, including the validation tests, especially at cryogenics temperature.

TL;DR: In this paper, the electrical insulation of the 1232 dipole diodes and diode busbars is presently consolidated during the second long shutdown of the LHC in 2019 and 2020, and the newly designed insulation system, mainly consisting of polyimide laminated fiber reinforced epoxy sheets and injection molded pure resin inserts, can be installed in the very constricted space of the lHC tunnel, without removing the presently installed insulation.

TL;DR: In this article, the authors present design options concerning the integration of the busbars inside the coldmass with a fixed point, and a reinforced insulation system for the flexible busbar part using thin PEEK tubes.
