Development and Application of Sub-nanosecond Pulse-repeatable Hard X-ray Source
【摘要】 为获得一种多用途X射线源,满足核辐射探测器研制、脉冲成像等多任务应用需要,本文研制出具备重复频率、超快、高稳定性、便于连续调节脉冲电压和脉宽等的多用途X射线源,其上升沿达98.6ps,运行电压达425kV,10cm处峰值注量率高达2.07×1018 cm-2.s-1,为开展相关应用研究提供了理想的辐射条件。
【Abstract】 A multipurpose X-ray source was developed to meet the needs of multitask application such as radiation detection,radiation imaging and so on.The multipurpose X-ray source has characteristic of adjustable width and energy,pulse-repetition operation,ultra-short pulse and fine stability.Its rising time is close to 98.6 ps,the operation voltage reaches 425 kV,and the peak fluence rate exceeds 2.07×1018 cm-2·s-1 at 10 cm,which provides an ideal radiation environment for relevant application.
