Harmonic Coil Magnetic Measurement System for HESR Magnets − a Mathematical Model and Design

This paper presents the constructive design of the Sextupole, Horizontal Steerer and Vertical Steerer electromagnets manufactured by ICPE-CA for HESR storage ring from FAIR Project which will be set-up in Darmstadt Germany. Also, in this paper is presented the current method and system with Hall probe the one that we have performed the magnetic measurements so far by now. Regarding that this method takes a lot of time to perform the magnetic measurements, meanwhile we have developed a system with harmonic coils, which we intend to use in the further magnetic measurements. Also, in this paper is presented the method of magnetic measurements with harmonic coil also the development of mathematical model for this measurement method. To validate the mathematical model of magnetic measurements using harmonic coils we have made a simulation and we have compared with the measurements performed with Hall probe on the Sextupole electromagnet.
