摘要： An electron gun apparatus comprises a cathode subassembly which is movably mounted relative to a fixedly mounted and registered grid/anode subassembly to permit mechanical adjustment of the cathode with respect to the grid/anode subassembly. An evacuated chamber, including resilient bellows interconnecting the movably mounted cathode assembly to the fixedly mounted grid/anode subassembly for permitting the mechanical adjustment, houses the cathode and the grid/anode subassemblies. Means are provided for electrical energization of the cathode, the grid, and the anode. According to a further feature of the invention, the cathode comprises a line filament, and the grid and the anode are slotted for providing an elongated line image.
