title: Expandable flash x-ray tube (FXT) having a 0.5-mm source size.
abstract: An inexpensive, expandable, continuously pumped, all-metal flash x-ray tube (FXT) was developed. It was coaxialy integrated at the end of a 70-Omega flexible coaxial transmission line. The tube, which has a small, 0.5-mm, x-ray source size when operated at 200 kV, produces a dose rate of 5x10(7) R/s (at exit port). The produced x-ray pulse has a duration of 20 ns, thus permitting the radiography of high-speed transient phenomena.
