Abstract
The electron gun comprises an electron lens assembly including a pair of terminal electrodes fixedly mounted along a pair of glass support rods. Disposed between the terminal electrodes is a resistive lens stack of alternate apertured electrode plates and resistive spacer blocks. The electrode plates and resistive spacer blocks are urged into good electrical contact with each other and with the terminal electrodes by a plurality of leaf springs. The electrode plates are preferably lightly contacted by the glass support rods to prevent lateral movement of the plates without preventing their spring-urged contact with the resistive blocks.
