Abstract
The transient signal which results from the characteristics of a low-velocity electron beam and the capacitance of the scanned surface has been calculated. A very slow transient of the hyperbolic type can result if the scanned surface is stabilized at a retarding field potential. The calculations have been verified by tests on a 6198 Vidicon, which was taken as an example. For this tube, the relative contributions of the "electronic transient" and the photoconductive decay to the observed transient response were determined. They make comparable contributions to the total transient.
