Abstract The invention relates to an improvement in a method of gas plating the walls of channels of a multi-channeled election amplifying element by thermal decomposition of a metal plating vapor continually directed through said channels which comprises the steps of preheating said plating vapor to nearly its decomposition temperature prior to entrance thereof into said channels of said elements and intermittently heating said element to a temperature at least equal to that of the decomposition temperature of said plating vapor and allowing said element to cool to a temperature below said decomposition temperature during said intervals between said intermittent heating to effect flushing of said residue gases of said vapor in said channels by said continuous flow thereof during said intervals.

Claim 1
Independent Claim
114 words
IN A METHOD OF GAS PLATING THE WALLS OF CHANNELS OF A MULTI-CHANNELED ELECTRON AMPLIFYING ELEMENT BY THERMAL DECOMPOSITION OF A METAL PLATING VAPOR CONTINUALLY DIRECTED THROUGH SAID CHANNELS, THE IMPROVEMENT COMPRISING THE STEPS OF: PREHEATING SAID PLATING VAPOR TO NEARLY ITS DECOMPOSITION TEMPERATURE PRIOR TO ENTRANCE THEREOF INTO SAID CHANNELS OF SAID ELEMENT; AND INTERMITTENTLY HEATING SAID ELEMENT TO A TEMPERATURE AT LEAST EQUAL TO THAT OF THE DECOMPOSITION TEMPERATURE OF SAID PLATING VAPOR AND ALLOWING SAID ELEMENT TO COOL TO A TEMPERATURE BELOW SAID DECOMPOSITION TEMPERATURE DURING INTERVALS BETWEEN SAID INTERMITTENT HEATING TO EFFECT FLUSHING OF RESIDUE GASES OF SAID VAPOR IN SAID CHANNELS BY SAID CONTINUOUS FLOW THEREOF DURING SAID INTEVALS.
Claim 2
Dependent Claim
