Abstract

A magnetic control pulling single-crystal superconducting magnet for conduction cooling comprises a coil framework, and an arc section of the coil framework is connected with a left and right coil cold conduction connecting device. The upper side of the left and right coil cold conduction connecting device is provided with a cold shield cold conduction device, and the lower side of the left and right coil cold conduction connecting device is provided with a coil cold conduction device; the first-stage cold head of a G-M refrigerator is connected with the second-stage cold head of the G-M refrigerator through a heat pipe; and the upper side of the cold shield cold conduction device is connected with the G-M refrigerator. The cooling method comprises the following steps: 1 setting the cooling magnetic control pulling single-crystal superconducting magnet; 2 filling the heat pipe with gas, and starting the G-M refrigerator to cool a test sample; and 3 achieving rapid cooling of the superconducting coil. The cooling method has the characteristic of high cooling efficiency.

Description

technical field [0001] The invention belongs to the technical field of magnetically controlled single crystal application, and in particular relates to a superconducting magnet used for conduction cooling and magnetically controlled single crystal and a cooling method thereof. Background technique [0002] High-purity monocrystalline silicon is widely used in solar cells, integrated circuits, semiconductors, and other industries. It is one of the key materials for high-tech industries such as photovoltaic power generation and electronic information. It has an important strategic position in ensuring energy, information, and national security. However, due to the core component of the magnetic pulling single crystal technology - large superconducting strong magnet device, its design technology is difficult, the processing and manufacturing is difficult, the cost and risk are high, etc., resulting in the lack of relevant basic research and technology accumulation in China. Thi...
