Paper Abstract

Electronic streak cameras are used to record subnanosecond data at the Nevada Test Site. It has been found that externally induced variations in the photocathode voltage of the streak tube can produce both temporal and spatial errors on the output image. An elec on beam tracing code was used to model the magnification as a function of photocathode voltage and signal input position for streak tubes manufactured by RCA, ITT, and Kentech. Las tests were also performed where pulsed and radio frequency signals were induced upon the photocathode and the errors on e resultant image were compared with e error sredict-s by the electron II - am code. Also, methods for processing the distortion in digitized images were investigated. This pas r will discuss the results of these investigations.
