Review of flash X-ray generator applied to hydrokinetical experiments

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.
