| Abstract | ||
| A new design of electron gun has been developed to study the effect of the curvature shape of the opposite electrodes faces on its optical and operational performance. Convex and concave arc shapes of different radii and orientations of the electrodes faces combined to design a series of electron guns geometries including the flat shape of the electrode face. Each model has been studied extensively to obtain the optimum electrode curvature shape. It has been found that it is possible to improve the current density and other optical properties of the electron gun by choosing suitable arc shape and radius for the confront electrodes. | ||
