Advanced Electron Beam Diagnostics.
Abstract
An experimental study was conducted to determine the feasibility of using two pyrometric techniques to provide diagnostic tools for electron-beam irradiation experiments. In one technique, an image converter camera was used to photograph the self-luminescent surface of irradiated specimens at various times after the end of irradiation. This instrument determined the spatial distribution of target temperature on the front and back faces of specimens in beam fluences up to target vaporization. In the other technique, optical pyrometry was used with several channels observing different wavelengths and/or target points. Both fast photomultipliers and a silicon diode (IR) were used to measure the self luminescent light from the test specimen irradiation which was then correlated with temperature. The results of tests conducted at the Boeing Radiation Effects Laboratory are reported and analyzed, and demonstrate the feasibility and limitations in use of these techniques. A qualitative study of the luminous sources in an electron beam irradiation environment is also given. (Author)
