重复频率脉冲强X射线源
-
摘要: 介绍了一台重复率1~2Hz、采用等离子体断路开关和电感储能技术的脉冲强X射线源。距辐射靶0.5m处的峰值剂量率为0.25MGy/s,1m处的平均剂量率为0.15kGy/h,脉宽(FWHM)约为100ns。给出了装置构成、原理及初步调试结果。Abstract: A repetitive pulsed intense X-ray source operating in 1~2Hz is described briefly. It is utilized the technology of repetitive plasma opening switch(RPOS) and Inductance Energy Storage. After RPOS opening swiftly, a high-voltage pulse reaching ~3MV is imposed on the bremsstrahlung radiating source diode and produced a intense X-ray pulse. The X-ray pulse parameters as following : peak dose-rate is 0.25MGy/s at 0.5m , average dose-rate is 0.15kGy/h at 1m, Full Width of Half Magnitude (FWHM) is ~100ns. The configuration, priciple and preliminary results are given in this paper.
