1.8 T compact type direct current magnet with low power consumption and high field

Abstract

The invention discloses a 1.8 T compact type direct current magnet with low power consumption and high field. The 1.8 T compact type direct current magnet comprises a copper-tape winding, a magnet yoke, a binding post and a sealing cylinder, wherein the copper-tape winding is arranged inside the magnet yoke, the copper-tape winding is wound by using copper tapes, the copper tapes are insulated from one another, and a plurality of groups of copper tapes are arranged from inside to outside; certain intervals are formed among the groups of copper tapes; gaps are arranged at two ends of the coppertapes, and an insulating part is placed inside each gap; a water inlet is formed in the interior of the magnet yoke, and a water outlet is formed outside the magnet yoke; a slot is formed in the insulating part; a first binding post is led out on the magnet yoke, and a second binding post is led out from the interior of the water outlet; the sealing cylinder is arranged at the opening position ofthe magnet yoke, and the sealing cylinder is connected with the copper tape on the innermost layer together. The direct current magnet has the effects that a magnetic field is restricted and guided by using a ferromagnetic material, the magnetic field is concentrated in an effective area, the volume of the magnet and the power consumption of the copper-tape winding can be greatly reduced, an S-shaped rotary water route is formed, and the copper-tape winding can be cooled sufficiently. The direct current magnet is low in power consumption, small in volume and sufficient in cooling, and stabledirect current operation can be realized.

Description

technical field [0001] The name of the invention is a 1.8T large-aperture low-power strong-field DC magnet, which can generate a 1.8T strong magnetic field at room temperature and can be used to provide a magnetic field for a gyrotron or other scientific experimental devices. Background technique [0002] The gyrotron is a fast-wave device, which overcomes the limitation of the physical size of the resonance region when the traditional slow-wave device works. In the millimeter wave band and the terahertz frequency band, the gyrotron is the only device that can generate high-power continuous wave output. But gyrotrons require a very strong magnetic field to work, often requiring superconducting magnets. However, superconducting magnets need to be kept at a low temperature, the preparation time is long, and the continuous cooling power consumption is large, which greatly limits the practicability. In order to reduce the requirement of the gyrotron to the magnetic field, a fe...

Problems solved by technology

[0004] Conventional copper tape windings have a large magnetic field and high power consumption, exceeding 100kW, making it difficult to cool effectively. Usually, they can only work continuously in pulse mode or for a short time.
