Investigation Of Material Movement Within Steel test sections by means of high speed x-ray photography

In simultation experiments the consequences of hypothetical reactor accidents are investigated. The materials involved in the tests, as well as the temperatures, require test sections of steel. To follow the materials movement and relocation X-ray cine equipment was developed. The test section is radiated from three axially positioned. X-ray sources, electro optical image amplifiers transform the material density distribution into a visible picture, which is picked up by high speed cameras with, typically, 1000 pictures per second. The resolution of the system is about 1 mm3 of steel with a small dependance on the total thickness of the test section. The technique, its main features and limitations are described and some experimental results are presented as an example. The computer aided analysis of the X-ray high speed films is also explained.© (1983) COPYRIGHT SPIE--The International Society for Optical Engineering.
