An electronically controlled vector magnetic field device and its installation method

Abstract

The invention relates to the technical field of precision actuation, in particular to an electronically controlled vector magnetic field device and an installation method thereof. It includes a sample stage on which a sample holder is arranged; a magnetic field control mechanism, the magnetic field control mechanism includes a moving part and a driving part that drives the moving part to perform precise linear motion, and the end of the moving part is loaded with a permanent magnet, The extension lines of the moving direction and the polarization direction of the permanent magnet are perpendicular to the center of the sample holder. The invention controls the precise actuation of the permanent magnet in one direction through the magnetic field control mechanism, and precisely controls the permanent magnet to approach or stay away from the sample on the sample holder, thereby realizing precise control of the magnetic field intensity of the sample. The electronically controlled vector magnetic field device of the invention has the advantages of compact structure, high braking precision and large magnetic field control range.

Description

technical field [0001] The invention relates to the technical field of precision actuation, in particular to a precision electronically controlled vector magnetic field adjustment device and an installation method thereof. Background technique [0002] Precision actuation refers to the technology that controls the load to move along the specified direction to achieve nanoscale precision, generally including linear actuation and rotation. This technology has been widely used in precision surface characterization, optical positioning adjustment, micro-nano processing and other fields. For the study of the scientific properties of surfaces under electromagnetic fields, a set of magnetic field control devices integrated in the scanning probe of the scanning probe microscope system is extremely necessary. On the one hand, we need to achieve continuous and precise regulation of the magnetic field strength and direction; on the other hand, the device itself must be compact and rob...

Problems solved by technology

At present, the existing commercial precision motion control consoles are large in size, complex in structure, and poor in shock resistance. They cannot be compatible with the limited space inside the scanning microscope probe, and cannot meet the high shock resistance requirements of scanning probe technology, which greatly limits Surface Science Research in Electromagnetic Field Environment
