Abstract
The experimental study of matrix carbon field-emission cathodes (MCFECs), which has led to the stable operation of the cathodes with current emission values up to 100 mA, is described. A method of computer aided design of TWT electron guns (EGs) with MCFEC, based on the results of the MCFEC emission experimental study, is presented. The experimental MCFEC emission characteristics are used to define the field gain coefficient K and the cathode effective emission area Seff. The EG program computes the electric field upon the MCFEC surface, multiplies it by the K value and uses the Fowler–Nordheim law and the Seff value to calculate the MCFEC current; the electron trajectories are computed as well.
