放电过程中脉冲磁体的热传导

对脉冲磁体放电过程中的热传导进行理论分析与实验测试，结果表明：对于短脉冲磁体，采用绝热模型与考虑热传导后的模型所得计算结果相近，并且二者均与实验测量得到的结果相符；对于长脉冲磁体，由于热传导时间相对较长，绝热模型计算得到的温升与考虑热传导后模型得到的温升有较大差别。通过理论分析可知：无论是短脉冲磁体还是长脉冲磁体，放电过程中的热传导只对磁体温升分布有较大影响，而对磁场波形则几乎没有影响。

Thermal conduction during discharge process in pulsed magnet

Theoretical analysis and experimental study have been carried out on the thermal conduction during the discharge process in pulsed magnets. The simulation results show that, for the short pulse magnet, the results obtained from models with and without thermal conduction agree well with each other. The results from theoretical analysis and experiments are also in good agreement. For the long pulse magnet, the temperature difference between models with and without thermal conduction becomes non-negligible. The theoretical analysis shows that, for both short and long pulse magnets, the thermal conduction influences only the temperature distribution, not the waveform of the pulse magnetic field.
