Wire positioning device and method based on quadrupole magnet and vibrating wire technology

Abstract

The invention provides a wire positioning device based on a quadrupole magnet and the vibrating wire technology. The wire positioning device comprises a quadrupole magnet having a magnet hole in the center, a uniform gradient magnetic field being formed in the magnet hole, and the quadrupole magnet being externally provided with a plurality of reference members; a magnet position adjusting mechanism located at the bottom of the quadrupole magnet for position adjustment of the quadrupole magnet in horizontal and vertical directions; and a wire vibration monitoring system, which comprises two sensors for monitoring the amplitude and phase of a wire in the horizontal and vertical directions, a sensor position adjusting mechanism for carrying the two sensors and for position adjustment, a signal collecting device for collecting voltage signals output by the two sensors, and a wire vibration excitation device for providing the wire with an AC signal of a specific amplitude and frequency. The invention also provides a wire positioning method based on the quadrupole magnet and the vibrating wire technology, which uses the device to position the wire.

Description

technical field [0001] The invention relates to the field of magnetic measurement and alignment of accelerators, in particular to a wire positioning device and method based on a precisely calibrated quadrupole magnet and a vibrating wire technology. Background technique [0002] In the fields of accelerator magnetic measurement and collimation, there are more and more applications of thin wires. The material of thin wires is metal, and the diameter is usually about 0.1 mm. An application such as a vibrating wire requires measurement of the position of the wire, since the position of the wire represents the position of the magnetic center of the field element. After the magnetic center position of the magnetic field element is detected by the wire through the vibrating wire technology, the positional relationship between the wire position and the magnetic field component equipment is calibrated by the laser tracker, and the magnetic field component equipment is installed in t...
