EGUN (Electron Optics Simulations)

EGUN is a world famous simulation tool, developed by Bill Herrmannsfeldt at Stanford Linear Accelerator Center (SLAC), for the numerical simulation of electron guns, including space charge, Child-Langmuir and Fowler-Nordheim starting routines and 3D relativistic trajectory calculation in 2D rectangular or axially symmetric electric and magnetic fields. The program provides graphic output files for electrodes, equipotential lines, and trajectories. Diagnostic graphics shows the profile of current density and RMS-emittance. Mesh size is made by internal memory allocation. Maximum mesh size is only limited by available memory.
