摘要
介绍了一种新型辐照加速器——花瓣形加速器NB100(10 MeV/100 kW)。用电磁场3维仿真软件模拟计算了此种加速器加速腔的高频特性参数,研究了腔体特性参数与几何尺寸的关系,在考虑电子束渡越时间情况下,优化出了一组频率为100 MHz时的加速腔结构其尺寸为:腔体高度1 547 mm,外筒内半径980mm,内筒外半径240 mm,内筒倒圆角半径210 mm,外筒倒圆角半径110 mm。计算结果表明:该种新加速腔具有较高的有效分路阻抗和品质因数。
This paper introduces a new type Irradiation accelerator-petal-shaped radiation accelerator NB100（10 MeV/100 kW）. The RF characteristic parameters of the accelerating cavity of NB100 was simulated with Microwave Studio. The relation-ships between the RF characteristic parameters and the geometrical parameters were studied. The paper optimizes the 100 MHz accelerating structure considering the transit-time of electron beam. The results show that the new type accelerating cavity has relatively high effective shunt impedance and quality factor.
