Superconducting radial thick coil for superconducting cyclotron, and winding and dipping method of superconducting radial thick coil

Abstract

The invention discloses a superconducting radial thick coil for a superconducting cyclotron. The superconducting radial thick coil is characterized in that a pretightening force in the winding process of an upper superconducting coil and a lower superconducting coil does not form coil quenching due to too tight or too loose pretightening force, and epoxy resin cannot flow in easily; and the pretightening force, the consistency of the pretightening force and the consistency of the direction of the pretightening force ensure that the upper coil and the lower coil are coaxial and parallel and do not exceed 0.1 mm, and four beam leading-out holes which are uniformly distributed at 90-degree intervals are formed in a beam channel of the coil framework. The invention further discloses a method which comprises the following steps of: 1) in the coil winding process, controlling the pretightening force to be smaller than or equal to 12 kgf, and controlling the direction of the pretightening force to be consistent, so that the parallelism of the interior of each coil and the parallelism between the coils reach 0.1 mm; and (2) by controlling the pretightening force to be smaller than or equal to 12 kgf and controlling the pretightening force to be consistent, the coaxiality of the interior of each coil and the coaxiality of the coils reach 0.1 mm. Therefore, the problem of coil quenching is solved, and the problem of magnetic field uniformity is solved.

Description

technical field [0001] The invention belongs to the technical field of superconducting cyclotrons, and in particular relates to a superconducting radially thick coil for superconducting cyclotrons and a winding and impregnating method thereof. Background technique [0002] The magnetic field of the superconducting cyclotron is mainly provided by the superconducting coil. Due to the large magnetic field required, the radial thickness of the superconducting coil is relatively thick, which makes it very difficult to manufacture. [0003] The first production difficulty: Since the superconducting coil is very thick and high, it is difficult to flow the epoxy resin from the outside to the inside along the radial direction: compared with other superconducting coils, the diameter of the cyclotron superconducting coil is The ratio of the radial width to the coil height is generally 2:3 or even 1:1. The reason for the radially thicker coil is that the coil excitation amp number is la...
