The horizontal displacement of the circulating beam during injection relies on 4 pulsed dipole magnets. During the initial run of the new magnet system, non-conformities have been observed. These could be traced back mainly to early fatigue effects, some of which were in brazed joints on the coil cooling circuit. An extensive program has been launched to improve the brazing technology for the spare coil manufacturing. This effort has been combined with numerical computations as well as destructive and non-destructive testing of brazed joints, allowing to identify critical stress domains resulting in fatigue sensitive areas. This paper describes the applied methodology and implements measures to increase the robustness of the magnet coils. The achieved improvements have been validated by testing based on an instrumented coil, allowing to correlate stress-strain measurements with results from the structural and transient numerical computation.
