Two high-voltage, high-power Pierce-type electron guns were designed and developed for use at the NRL high-power ubitron laboratory. The design of the high-voltage and vacuum housings of the guns incorporates design features utilized in the XK-5 klystron gun. Detail design data and beam trajectories are presented. Beam analyzer and high voltage tests are discussed. Assembly and detail drawings are included. Keywords Electrostatic beam optics Electromagnetic beam optics Electron trajectories Voltage Gradient Confined- flow magnetic focusing field Ubitron Computer gun design program Laminar beam Beam axial velocity spread Gun coil Computer controlled beam analyzer.
