Abstract :
Iterative and noniterative synthesis techniques are widely employed for the preliminary design of Pierce electron guns, depending on four commonly used input design beam parameters. In this brief, an improved noniterative approach is proposed. This approach results in much closer agreement with the measured values of the same, except the anode-cathode spacing, when compared with 30 practical Pierce guns of different performances
