GEOMETRICAL OPTIMIZATION OF CATHODE WITH DIRECT HEATING FOR POWER MAGNETRONS BY USING OF LINEAR THERMAL COMPENSATOR

摘要

The paper has presented an optimization method for a cathode with direct heating of power magnetrons. The method consists in heterogenic weld with Pt addition of jointing between spiral filament and reflectors lids and in to obtain of correlation between thermal dilatation coefficients of spiral filament and cathodic core. The thermal compensator assures taking over of different temperature gradients and dilatation coefficients of ensemble avoids deformation of contact points and protected jointing weld and rest elements, improving the cathode reliability and working of magnetron.
