摘要: 闪光X光机是流体动力学等研究领域必不可少的实验诊断装置, 物理需求推动其向更高剂量和更小焦斑发展。叙述了几种X光二极管研究现状和关键问题，阐述了适用于不同功率水平的闪光X光机驱动源，分析了阳极杆箍缩和磁浸没二极管的应用前景，讨论了阳极杆箍缩二极管、驱动源发展方向以及实现多幅照相涉及的关键技术。Abstract: Pulsed power driven flash X-ray generators are essential testing equipments in areas like hydrokinetics. Smaller spot size and higher radiation dose are expected according to physical requirements. Current status and key problems of several X-ray diodes are narrated, a pulse power supply driving X-ray diode from hundreds of MW to tens of GW is recited. Application prospects of rod pinch and magnetically immersed diode are analyzed. Moreover, advances of rod pinch diode and pulsed power supply, as well as key techniques realizing multi-frame flash radiography are discussed.
