Electric control vector magnetic field device and mounting method thereof

Abstract

The invention relates to the technical field of precision actuation, in particular to an electric control vector magnetic field device and an installation method thereof. The device comprises: a sample table, wherein a sample support is arranged on the sample table; a magnetic field control mechanism which comprises a moving part and a driving part for driving the moving part to do precise linearmotion, wherein a permanent magnet is loaded at the end part of the moving part, and the extension lines of the moving direction and the polarization direction of the permanent magnet are orthogonal to the center of the sample support. Precise actuation of the permanent magnet in one direction is controlled through the magnetic field control mechanism, the permanent magnet is accurately controlledto be close to or away from a sample on the sample support, and therefore the magnetic field intensity of the sample is accurately controlled. The electric control vector magnetic field device is compact in structure, high in braking precision and large in magnetic field regulation and 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
