Abstract:

The collector-to-backing electrode spacing seems to have little direct effect upon the stored resolution. However, it may be a factor in moire patterns which influence the low brightness resolution. This moire is believed to be a result of not only collector and backing electrode mesh numbers but also the spacing between them. Other factors affecting moire are the raster line spacing and rotation relative to these meshes. A definite improvement in resolution is achieved by reducing the transit time of electrons in the viewing screen-to-backing electrode space. This increase in resolution is limited by the gradient which can be established between the viewing screen and the backing electrode without voltage breakdown. An improved writing gun has been designed. Further tests and improvements are in progress. Author
