摘　　要：闪光X射线照相技术是研究动载荷及其效应的重要测试手段,特别适用于研究物质在爆炸作用下的瞬变过程,本文介绍了闪光Ⅰ号加速器应用于X射线爆轰照相的基本状况,以及用于观察金属射流穿过高密度物质钨靶的实验技术。Flash I machine is a 6MV REB accelerator. A hollow conical cathode is used to produce beam focusing in the diode and hence an intense bremsstrahlung radiation of 250R at 1 meter with a focus diameter of 6mm has been obtained. Using this accelerator, radiography of high density material under jet perforation was performed. Detonation experiments were carried out in a blast chamber. Results indicated that radiographic capability of this accelerator was more than 5cm tungsten. Details of the radiography technique are described.
