Abstract
The utility model relates to a measure multi -thread ring of circuit board that magnetic field distributes, include: the circuit board for install near the magnetic field of awaiting measuring, make by plastics, the B -DOT magnetic probe is installed on the circuit board, be used for measuring B -DOT magnetism is visited needle position and is put magnetic field a little. The utility model provides a multi -thread ring of circuit board can be applied to different plasma environment and measure, size and spatial distribution that can simultaneous measurement magnetic field.
Description
Technical field
The utility model relates to the fields of measurement of electromagnetic field space distribution, particularly relates to a kind of multi-coil circuit board measuring magnetic field space distribution.
Background technology
No matter be space celestial body plasma environment or laboratory plasma environment, plasma distribution in magnetic field all plays a very important role.The method of traditional measurement internal magnetic field size inserts little solenoid coil in the plasma, such as unicoil B-DOT magnetic probe, measured that strength of current is counter pushes away magnetic field size by Biot's Sa farr's law.
Single B-DOT magnetic probe can only the magnetic field of measuring probe place partial points, but often need the space distribution of a region internal magnetic field, especially in laboratory plasma environment.
Utility model content
The purpose of this utility model proposes a kind of multi-coil circuit board measuring magnetic field space distribution, effectively can measure size and the space distribution in magnetic field.
A kind of multi-coil circuit board measuring magnetic field space distribution of the present utility model comprises:
Circuit board, for being arranged near magnetic field to be measured, is made of plastics;
B-DOT magnetic probe, is arranged on described circuit board, for measuring the magnetic field of described B-DOT magnetic probe location point.
Preferably, described circuit board is rectangle, long 2 centimetres, wide 1 centimetre.
Preferably, described B-DOT magnetic probe number is 6, and discharge three according to line direction, column direction discharges two, is arranged on equably on described circuit board.
Multiple unicoil B-DOT magnetic probe is integrated on a wiring board by the utility model, like this can measurement space multiple positions electric current, thus can draw out spatial magnetic field.Measure Distribution of Magnetic Field in the experiment of this technology plasma and there is actual application value.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
In order to make the technological means of this device, creation characteristic, reach object and effect is easy to understand, below in conjunction with concrete diagram, be described in detail.
The utility model provides a kind of multi-coil circuit board measuring magnetic field space distribution as shown in Figure 1, comprising: circuit board 1 and B-DOT magnetic probe 2.B-DOT magnetic probe, is evenly arranged on plastics circuit board 1, then whole circuit board 1 is arranged near field region to be measured, utilizes magnetic probe B-DOT magnetic probe to measure the magnetic field of each B-DOT magnetic probe location point.
This integrated circuit board is fixedly placed near field region to be measured, in order to avoid infringement coil, usually instrument is placed and adopt cover plate to protect coil apart from magnetic field to be measured certain distance simultaneously.According to the law of electromagnetic induction, when coil place obtain Zhong get magnetic field, space change time, owing to obtaining magnetic flux change through coil section, obtain two ends at coil and can produce an induction electromotive force.Signal is drawn by anti-interference lead-in wire, in high-frequency oscilloscope measurement electric potential difference, the electromotive force of record every bit position,
magnetic field data is obtained by integration.
This multi-coil circuit board can be applied to static magnetic field, and dynamic magnetic field is as laser plasma, magnetized plasma, the measurement of the physical environments such as low temperature plasma.The size and spatial distribution characteristic etc. in magnetic field can be measured simultaneously.
The concrete shape size of the utility model circuit board, the number of B-DOT magnetic probe, size and disposing way can change according to concrete field region environment to be measured.
