Abstract
A high resolution three-frame flash x-radiography (FXR) system has been developed for studies of intense ion beam driven Inertial Confinement Fusion pellet implosions. This system consists of three independently triggered micro-point [ ~100 4m spot size] FXR sources and three lead shielded collimating cameras. Each of the FXR sources has a 3 ns output pulse that is characteristic of a 600 keV tungsten bremsstrahlung spectrum. The sources and the cameras are arranged with equal azimuthal angular spacing on a 12° half angle biconic surface. With this system, three time-separated and 3X magnified x-radiographic images of the imploding target with 100 p.m spatial resolution and 2.6 ns temporal resolution can be made. Targets moving as fast as 3-4 cm/4s can be recorded without motion blur. Studies of high Z metallic spherical and cylindrical targets imploded by an intense ion beam have been carried out. Results show that ablatively driven puher velocity as high as 1 cm/4s can be achieved with an ion beam intensity of 0.5 TW/cm on target.
