Peculiarities of operation of secondary electron emission cathodes and different types of their excitation are discussed. On the base of available experimental data possibilities are analyzed for obtaining maximum achievable beam currents and densities. It is shown that the cross-field geometry is best-suited for achieving the highest current densities and peak beam currents. Experimental observables as regards beam characteristics of the secondary-emission magnetron gun (SEMIG) are presented. Prospects for obtaining beam current densities in excess of 100 A/cm{sup 2} at beam current above 100 A are discussed for cathode life times 20 to 100 thousand hours. {copyright} {ital 1995} {ital American} {ital Institute} {ital of} {ital Physics}.
