本发明公开了一种直线感应加速腔结构，包括铁磁室，铁磁室内设有磁芯组，磁芯组包括铁氧体磁芯和非晶磁芯。本发明与现有技术相比，具有如下的优点和有益效果：横向阻抗大大降低，不需要像常规非晶磁芯感应腔那样采用增加束管道半径的方式来降低非晶磁芯感应腔的横向耦合阻抗以满足强流束的输运要求；铁氧体磁性材料近似绝缘材料且它将非晶磁芯与高压馈入板隔开，这大幅度增加了非晶磁芯感应加速腔的耐压能力；结构紧凑、可靠，既可用于短脉冲，也可用于长脉冲、多脉冲等需要提供更多伏秒数的情形；与现有感应腔相比，可以减小磁芯的用量，提高加速梯度，减少加速器的长度，利于强流束的传输，同时大幅降低加速器的造价。 The invention discloses a novel linear induction acceleration cavity structure, which comprises a ferromagnetic chamber, a magnetic core group is arranged in the ferromagnetic chamber, and the magnetic core group comprises a ferrite magnetic core and an amorphous magnetic core. Compared with the prior art, the structure has the following advantages and beneficial effects that the transverse impedance is greatly reduced, and the transverse coupling impedance of the amorphous magnetic core induction cavity does not need to be reduced in a mode of increasing the radius of a beam pipeline like a conventional amorphous magnetic core induction cavity so as to meet the transportation requirement of a strong flow beam; the ferrite ma
