| Abstract: | The influence of the configurational and electrical parametersof all-electrostatic camera tube with three electrodes on the focusing and de-flecting properties of the election beams is discussed by CAD. 26 mm(1 inch)camera tube is designed, and three expetimental sample tubes are made. Thetest results of the experimental tubes are as follows:amplitude response valueis 40 percent at 400 TV Lines in the picture center,geometrical distortion isless than 1 percent,signals are uniform and free from shading. The possibleways to improve the properties of the tube are discussed. |
