摘要：

This report presents the results of experimental investigations of cathode-grid structure based on CNTs. The experimental samples of field emission cathode-grid array based on vertical-aligned CNT with the cell of 1 um diameter and with 5 um pitch of microstructure are fabricated. The electron focusing system with a sheet CNT cathode with linear convergence 14, and with the beam current density of 78.4 A/cm(2) has been designed in terms of experimental data of a current voltage characteristic of the cathode.
