DEVELOPMENT OF A HYPERVELOCITY IMPACT DATA RECORDER.
Abstract
Methods of recording 14 or more X-ray or gamma ray shadowgrams of a single hypervelocity impact event were studied. Desired exposure times were as short as 0.02 microseconds. The power and pulse length limitations of a commercially available flash X-ray tube were experimentally determined and recommendations for extending the pulse length are presented. Two radioactive isotope sources, Co60 and Cs137 were studied and found to be impractical because of the excessive intensity levels required. Breadboard models of two detection and recording systems employing scintillator arrays and screens as detectors, and image intensifiers as shutters and light amplifiers were built and evaluated. Present limits and apparent direction of the most fruitful future effort are given for the critical problems of X-ray pulse length and detector sensitivity and intensity resolution. (Author)
