The effect of the current distribution across the electron beam on beam discharge lag and resolution capability of camera tubes are investigated analytically and experimentally. It is found that the resolution capability and beam discharge lag are dominated by both the current density distribution, especially at the leading edge, and by the equivalent temperature of the scanning electron beam. Experimental results show that a rectangular beam, cross section with 100 μm (horizontal size)×40 μm (vertical size) on the target, can resolve more than 800 TV lines in standard scanning format fat a 1 inch diameter tube (1/2" wide × 3/8" high) and also reduce beam discharge lag, for example to about 30% compared with that for a narrow beam at the same beam temperature.
