Abstract :
It is known that the presences of the grid electrodes in a Pierce-type electron gun disturbs the local fields and, consequently, the beam focusing properties. To illustrate the manner in which the beam laminarity characteristics are modified, we employ an hybridized 3D/2D approach to gridded gun-simulation which includes relativistic kinematics and a flux function treatment of the magnetic fields with provision for PPM focusing.
