Summary
The Vibrating Wire (VW) magnetic field measurement technique is based on the phenomenon of excitation of the stretched wire vibrational modes by Lorenz forces between AC electrical current flowing through the wire and surrounding magnetic field. The technique allows to measure magnetic field along the wire using information on the wire vibration amplitude and on the phase between wire vibration and driving AC current.
Because the VW technique employs a thin stretched wire as a magnetic field sensor, it is ideal to use in case of magnets with small apertures. The technique has extraordinary sensitivity and is most suitable for accurate magnetic axis finding. In many occasions, the method has been used for high-precision alignment of quadrupole, sextupole and solenoid magnets.
In the talk I will present the theory and describe applications of the technique.
