Paper Abstract

Electronic imaging has been undertaken upon a selection of AWE's high power x-ray pulse accelerators used for radiation effects testing on electronic components and small sub-systems. Principally an experimental configuration, based upon a pinhole scintillator combination, has been implemented to test the feasibility of recording by an electronic imaging system for high energy (3MeV) and high dose (>16krads) x-ray pulse sources. Recording by CCD based imaging technology has been used to image and verify the uniformity of the bremsstrahlung source. The accelerators of interest are the Short Pulse Experimental Electron Device (SPEED), which is a 1 MeV, very short (15 ns) pulse, high dose, bremsstrahlung source and the accelerator EROS (Energetic Radiation Of Samples), which is a 3 MeV, 40 krad, 85 ns pulse source. Quantification of Scintillator and camera parameters are highlighted in the paper and the unique electronic images, of the respective sources, are presented. Some future temporal imaging concepts with resolution approaching one nanosecond are also highlighted. The fundamental principles of the imaging system can be applied to other pulsed x-ray scenarios.
