Description
technical field [0001] The invention relates to a pull rod for a superconducting magnet, in particular to a pull rod for a space superconducting magnet. Background technique [0002] A magnetic spectrometer is a commonly used particle detector in high-energy physics research. It can measure the deflection of charged particles in a magnetic field, obtain the energy spectrum of high-energy cosmic rays in the outer space of the earth's atmosphere, and determine the elements in cosmic rays. and isotope content. The ultra-sensitivity properties of magnetic spectrometers to matter facilitate space exploration of dark matter and antimatter, and may lead to new breakthroughs in particle physics. The core component of a magnetic spectrometer is a permanent or superconducting magnet. Compared with permanent magnets, superconducting magnets have the advantages of small size, light weight, low energy consumption and high magnetic field strength. The advantages of small size, light we...
