We performed validation of a 3d Opera Space Charge simulation of a spherical Pierce gun using the Opera Maxwell Random Velocity Sampling emission model. Of particular interest is the potential minimum near the space charge limited cathode surface. We validated the simulation by comparing the results of the Maxwell Random Velocity Sampling Pierce gun simulation with published physical results.
