Abstract The magnetic field measurement technology is one of the core technologies of particle accelerators, and the harmonic field quality of multipole magnet is essential to beam transportation. The accurate and reliable magnetic field measurement data can provide important reference for installation, commissioning and operation of magnets for multi-purposes. Compared to relative lower positioning accuracy and repeatability by using traditional hand-wound coils, this paper introduces the design and implementation of a harmonic coil field measurement system based on printed circuit board (PCB) technology. The theory of harmonic field measurement, the design of PCB coil and mechanical support structure are described. A comparative study between the hand-wound coils and PCB coils are performed. The experimental results show that the PCB harmonic coils can achieve more stable and accurate magnetic field measurements with higher bucking rate, for harmonic magnetic fields measurement of multipole magnets. The research findings can provide a good reference for the design and development of harmonics field measurement coils based on PCB technique.
