| Abstract: | A design scheme of large aperture field magnet is provided based on the design requirements of the China Fusion Engineering Testing Reactor (CFETR) joints. Using the background field magnet to get the corresponding magnetic field data, the influence of the magnet parameter on the magnetic field is compared, and the corresponding magnetic field data are obtained. Gandalf program was used to simulate the shunt temperature of CFETR field magnet under operating conditions. Considering the hydrodynamic performance of liquid helium, Gandalf program was used to simulate the quench behavior of superconducting strands and to estimate the more accurate minimum quenching energy. The minimum quench value can be used as the Q0 value inputted into the program to obtain hot spot temperature value. The analysis shows that the design meets the requirements for the production of high temperature superconducting magnets and provide reliable basis for manufacture and experiments. |
