Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0027] Such as figure 1 As shown, a superconducting coil for a superconducting cyclotron provided by the present invention includes a cylindrical bobbin 1 wound with a superconducting thick coil 2, and the superconducting thick coil 2 is wound with a superconducting wire, wherein, A coil frame end plate 3 is arranged at one end of the coil frame 1 , and several flow guide grooves 4 are arranged on the coil frame end plate 3 , and epoxy resin is impregnated on the superconducting wire.

[0028] The flow guide groove 4 is evenly arranged on the end plate 3 of the coil frame, and the flow guide groove 4 can pass through the liquid epoxy resin. In this embodiment, the diversion groove 4 is 2 mm wide and 1 mm deep, and the number of diversion grooves 4 is 12 (the interval between every two adjacent diversion grooves 4 is 30 degrees).

[0029] The coil fram...

Abstract

The invention belongs to the technical field of superconducting cyclotrons, and particularly relates to a superconducting coil for the superconducting cyclotron and a winding impregnation method of the superconducting coil. The superconducting coil for the superconducting cyclotron comprises a cylindrical coil skeleton on which a thick superconducting coil is wound, wherein the thick superconducting coil is formed by winding superconducting wires; a coil skeleton end plate is arranged at one end of the coil skeleton; a plurality of diversion trenches are arranged in the coil skeleton end plate; and epoxy resin is impregnated on the superconducting wires. By the superconducting coil and the winding impregnation method thereof, gaps between the superconducting wires wound into the thick superconducting coil can be completely filled with the epoxy resin, so that a ''quench'' phenomenon of the superconducting coil due to the gaps between the superconducting wires is avoided.

Description

technical field [0001] The invention belongs to the technical field of superconducting cyclotrons, and in particular relates to a superconducting coil for a superconducting cyclotron and a winding and impregnating method thereof. Background technique [0002] A cyclotron is a device that makes use of a magnetic field and an electric field to make charged particles undergo cyclotron motion, and is repeatedly accelerated by a high-frequency electric field during the motion. It is an important instrument in high-energy physics. The superconducting cyclotron is the core equipment of the current medical proton therapy accelerator. Medical proton therapy accelerators can treat tumors with protons and heavy ion rays in the microscopic world. It is the most advanced radiation therapy technology in the world today, and only a few developed countries have mastered and applied this technology. The research and development of superconducting cyclotrons has been launched in China, but ha...
