“…It is, however, likely that a planar salt bath was built according to the original concept [22], [23]. Mathematical corrections may have been made to translate the planar model to an axially symmetric configuration (as reported, for example, in [24]). Although accuracies better than 1% have been achieved with electrolytic bath experiments, a difficult aspect is the arrangement of side electrodes to impose the boundary conditions, especially when the bath is small [25].…”

“…This paper develops an accurate analytic theory of fields and electrodes in such conditions, here called the case of moderately focused and convergent flows, which complements (or supersedes) the existing design theory of rectilinear flows [5][6][7][8] converging to a point O c . This older flow design assumes that space charge is fully balanced by the focusing action of some specially designed electrodes, so, for classification, we call this case "strongly convergent flow."…”

Flow of particles in diodes is solved selfconsistently assuming an approximated system of flow lines, that can be easily represented by an analytic transformation in a complex plane, with assumed uniformity in the third spatial direction. Beam current compression is tunable by an angle parameter α(0); transformed coordinate lines are circular arcs, exactly matching to the curved cathode usually considered by rectilinear converging flows. The curvature of flow lines allows to partly balance the transverse effect of space charge. A self-contained discussion of the whole theory is reported, ranging from analytical solution for selfconsistent potential to electrode drawing to precise numerical simulation, which serves as a verification and as an illustration of typical electrode shapes. Motion and Poisson equation are written in a curved flow line system and their approximate consistency is shown to imply an ordinary differential equation for the beam edge potential. Transformations of this equation and their series solutions are given and discussed, showing that beam edge potential has a maximum, so supporting both diode (with α(0) =/~ π∕3) and triode design. Numerical simulations confirm the consistency of these solution. Geometrical details of diode design are discussed: the condition of a zero divergence beam, with the necessary anode lens effect included, is written and solved, as a function of beam compression; accurate relations for diode parameters and perveance are given. Weakly relativistic effects including self-magnetic field are finally discussed as a refinement.
