Abstract

Current x-ray imaging systems used in ballistic range measurements are single pulsed, one image per film plane systems. There is need for an ultra-high-framing x-ray system to capture multiple images at high frame rate from one location. The requirement is to produce multiple x-ray images on a single large (~36 inch) format scintillator screen that can be captured and stored electronically at a frame rate of up to 1 MHz. The refresh time of the screen should not exceed 1 microsecond and the storage medium should accommodate at least 100 frames. The x-ray imaging system should have adequate spatial resolution to image small, 1/8 inch, aluminum particles and the multi-pulse x-ray gun should have an x-ray energy level of 150 keV or greater. The imaging screen will be located in a shrapnel prone impact area and should be disposable (low cost) or have an alternate method of preventing damage to high cost components. In Phase I the critical aspects of the system will be demonstrated. Phase I will also include the conceptual design of a ultra-high-framing rate x-ray system meeting the above requirements. The anticipated benefit of this program is a major state-of-the-art advancement in high frame rate X-ray systems for military and industrial non-destructive testing applications. The initial commercial application is the ballistic range testing at AEDC. There are ballistic range and explosive testing facilities within DOD and DOE where this instrumentation would be of great value. In addition there are academic and industrial laboratories where x-ray imaging a ultra-high frame rates would be invaluable. The substantial commercial market is indicated by the technical societies on non-destructive testing and their meetings and symposia held annually on this subject.
