【摘要】 本文提出以双聚焦、无空间色散的设计原则,来代替常用的全消色差设计原则,使医用电子直线加速器的偏转磁铁能够具有更好的特性。为实用需要,探讨了缩短靶与磁铁出口的距离和改变入射角所引起的影响,以便减少旋转治疗头的回转半径和设计更轻巧的偏转磁铁。更多还原

【Abstract】 A double focusing, non spatial dispersion magnet design has been suggested to substitute the achromatic principle for improving the beam characteristics on target of the medical accelerator. The influences of reducing the distance between the target and magnet exit and the effect of changing injection angle of the magnet have been discussed to obtain the more compact deflecting magnet.更多还原
