Abstract :
The conditions for achieving maximal emission current in multipactors are investigated analytically on the basis of single-particle models with regard to the mirror image field. The possibility of increasing emission current are suggested. The experimental results of a 3 GHz alenotron research are considered. A current of 150 mA has been achieved.
