Limiting currents in planar crossed-field diodes have been studied for over 70 years [1]-[3] for B < B[Hull] and more recently for B > B[H] [4]. Recent simulations of cylindrical crossed-field diodes for anode/cathode radius ratios of 2 and 5 indicate that the limiting current curve in cylindrical diodes follows the planar theory and simulations very closely [5]. Newer simulations for larger radius ratios (10,20) show somewhat larger limits. A possible explanation for this behavior is also examined.
