Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0023] like figure 1 As shown, the superconducting magnet 11 of the present invention includes a double pie coil 1, a superconducting joint 2, a magnet current lead 3, a magnetic field shielding tube 4, a packaging cylinder 5, a magnet current lead groove 6, a magnet end plate 9 and an epoxy hole 10. Multiple double pie coils 1 are closely arranged along the coil axial direction, and the number of double pie coils 1 is determined by the required magnetic field. The uppermost end of multiple double pie coils 1 connected together is covered with a round pie shaped magnet end plate 9 . The diameter of the central hole 8 of the magnet end plate is equal to that of the central hole 7 of the double cake coil. Two rectangular magnet current lead slots 6 are symmetrically opened on the side of the magnet end plate 9 . Superconducting joints 2 are us...

Abstract

The invention discloses a superconducting magnet. The superconducting magnet comprises double-pancake coils (1), superconducting connectors (2), magnet current leads (3), magnetic field shielding tubes (4), a packaging drum (5), magnet current lead grooves (6) and an epoxy hole (10); a plurality of double-pancake coils (1) are tightly connected along axial directions of the coils, the double-pancake coils (1) are connected with superconducting belts (5) through the superconducting connectors to reduce heat, and the intensity of a magnetic field where the magnet current leads (3) are positioned is reduced through the magnetic field shielding tubes (4), so that electromagnetic force applied to the magnet current leads (3) is reduced. A circular cake-shaped magnet end plate (9) is sleeved at the upper ends of the double-pancake coils (1) which are tightly connected, and one end of each of two magnet current leads (3) at the upper end of the magnet end plate (9) is sleeved in each magnetic field shielding tube (4).

Description

technical field [0001] The invention relates to a superconducting magnet and a manufacturing method thereof. Background technique [0002] With the continuous development of new materials and low-temperature technology, the application of superconducting technology has been accelerated. The unique physical properties of superconductors have application advantages that other materials cannot match, such as zero resistance effect, that is, unimpeded current-carrying capacity and so on. At present, the high magnetic field superconducting magnet system has a wide range of applications in physics, chemistry and biology research. Traditional electromagnets are difficult to achieve or require a lot of energy and resources to achieve a high magnetic field, and the use of the zero resistance effect of superconductors can form a high magnetic field by combining multiple superconducting magnets. Such as the use of niobium titanium (NbTi) and niobium tritin (Nb 3 The magnetic field of...
