Development of a pulsed magnet measurement bench using the stretched wire method

In the scope of the renewal of its injection systems, the ESRF-EBS has decided to implement a new scheme using Non-Linear Kickers (NLK) magnets. These pulsed octupole like magnets are extremely sensitive to any misalignment of the conductors carrying the currents resulting in a degraded magnetic field quality. It is then important to characterize precisely the transverse magnetic fields of these magnets to avoid any perturbation during the injection process. A new method to measure pulsed magnetic field is being developed at the ESRF-EBS readapting the classical method of the stretch wire bench for permanent magnet. This paper presents the advancement of this project and the first results.
