    专利说明:

    The invention relates primarily to cryogenic technology and can be used in the field of optimization and improvement of operating conditions of conductive electromagnets. A solenoid design that contains several coaxially arranged coils made of solid electrically conductive material is known. the material of the cogs and placed parallel to the axis of the solenoid, with the number of channels increasing from the outer diameter to the inner diameter of the solenoid l. The disadvantage of this design is the difficulty of manufacturing a coil with a large number of channels, and the same impossibility of its use with respect to superconducting electromagnets. The closest to the proposed technical essence and the achieved result is the design of a superconducting electromagnet containing a multilayer spiral continuous winding made of superconducting material placed in a refrigerant, with cooling channels between the winding layers, with the layers parallel to the symmetry axis of the winding 2j . A disadvantage of the known design is the reduced reliability of the electromagnet, due to the uneven cooling of the layers, the winding due to the increased value of the resistance of the inner layers of the winding at the time of transition of the material of the winding of the electromagnet to the normal conductivity state. The purpose of the invention is to increase the reliability of an electromagnet by ensuring uniform cooling of the winding layers. The goal is achieved by the fact that in a superconducting electromagnet containing a multilayer spiral continuous winding made of superconducting material placed in a refrigerant with cooling channels between the winding layers, the layers parallel to the axis of symmetry of the winding, the width of the cooling channels increases from the outer winding layer to the inside. The drawing shows schematically the device. In a superconducting electromagnet containing a multilayer spiral continuous winding 1 made of superconducting material placed in a refrigerant with cooling channels 2 between the layers of the winding, the layers parallel to the axis of symmetry of the winding, the width of the cooling channels increases from the outer layer winding to the inner. The device works as follows. When an electric current flows through the winding of an electromagnet, the intensity of the magnetic field rotates from the outer winding layer to the inner one. When the field strength exceeds a certain critical value for a given superconductor material, the electromagnet winding changes to a normal state with the release of a large amount of heat. Transition of the winding to the normal state begins in the zone of the highest magnetic field strength, where cooling conditions do not allow lowering the temperature of the most heated sections of the winding In order to equalize the conditions for the transition of the winding parts to the normal state, the latter operating under the most severe conditions in the the increased magnetic field strength, is subjected to more intensive cooling by an increased channel, which ensures the circulation of coolant, for example, liquid helium. Thus, the rate of heat removal from the winding sections adjacent to the k channel of greater width increases, the winding operates in less stressful conditions, which increases the reliability of the electromagnet as a whole.
