【摘要】 简要介绍了在直线感应加速器(LIA)中对所用磁性材料的要求,列举了国外在LIA中使用金属玻璃(非晶磁性材料)替代铁氧体磁环的实例。在非晶和铁氧体磁环静态磁性能测试的基础上,对两种材料的脉冲性能做了深入研究,实验研究表明在脉冲状态下,两者的饱和磁密均远大于静态饱和磁密。这一现象对实际应用很有价值。更多还原

【Abstract】 The requirements of magnetic material in linac induction accelerator and the characteristics of amorphous and ferrite are described briefly in this paper. Some instances about using amorphous to replace ferrite material are reviewed in the paper too. Experimentations are carried out under static condition, in additional more researches are done based on pulse condition. It is concluded that both materials have higher satutration magnetic density under pulse condition than under static condition.更多还原
