IGUN (Electron Optics Simulations)
IGUN, which is a child program of EGUN, can simulate positive ion extraction from plasmas. IGUN has interactive (colored) graphics, e.g. equipotential lines and trajectories are seen on screen for each cycle of iteration, allowing the users to judge the convergence and saving time by breaking execution, if input parameters have been chosen wrong. Comprehensive plots of the results are available, e.g. a full emittance diagram, a diagram of fractional emittance against current, beam profiles in equidistant positions along the beam axis, and of surface fields along the problem boundary. A special feature of IGUN is the possible definition of curved dielectric boundaries within the frame of the integrated POLYGON type input of boundary.
