Abstract
The experimental study of matrix carbon field-emission cathodes (MCFEC s), which has led to the stable operation of the cathodes with current emission values up to 100 mA, is described. A method of computer aide d design of TWT, electron guns (EGs) with MCFEC, based on the results of the MCFEC emission experimental study, is presented. The experiment al MCFEC emission characteristics are used to define the field gain co efficient K and the cathode effective emission area S-eff. The EG prog ram computes the electric held upon the MCFEC surface, multiplies it b y the K value and uses the Fowler-Nordheim law and the S-eff Value to calculate the MCFEC current; the electron trajectories are computed as well.
