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98.6 ps，运行电压达425 kV，10 cm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 2.07×10¹⁸cm^-2•s^-1 at 10 cm, which provides an ideal radiation environment for relevant application.
