Research and Development of an Equipment for Cineradiography (Etude et Realisation d'un Equipment de Cineradiographie),
Abstract
Although the theory of cineradiography is very well known, it is not used much because it often requires large installations that are costly and not easy to learn how to use correctly. The authors describe an installation of flash-radiography which can obtain six images of a rapid phenomenon with the possibility of selecting a very short time interval between two pictures. The equipment includes six flash radiography instruments which deliver 20ns X-ray pulses. The voltage applied to the tubes does not exceed 300kV. The flash radiography tubes are connected to the high voltage pulse generators by co-axial cables. This configuration allows the X-ray sources to be placed close to each other, thus minimizing parallax. The time delay between the synchronization signal and an X-ray pulse, detected by a photo-multiplier tube, is measured with a precision of plus or minus 5 ns. Several examples are shown of the recording of shaped charge jets. (Author)
