A single stage magnetically focused image converter, having a nickel mesh at its first accelerating electrode, was constructed. An Shyphen;11 posthyphen;oxidized photocathode was processed in this image tube. The imaging properties of this type of image converter have been studied under static and pulsed conditions. The output image resolution was studied as a function of the pulse duration or the switching on time. The effect of the application of a pulse to the photocathode or the control grid on the output image resolution is also mentioned. The rsquo;Srsquo; distortion and pincushion distortion under pulsed conditions is also briefly described. Applications of this image converter in spark gap photography, plasma diagnostics, and beam crosshyphen;section photography of the 1.3 GeV synchrotron at Frascati are briefly mentioned.
