Title: Microwave process control through a traveling wave tube source

Conference ·
OSTI ID:219524

A rapid feedback control system was designed to operate with a traveling wave tube for regulating the sintering temperature of tows and tubes in a single mode microwave cavity. The control system regulated the microwave frequency and power absorbed by the sample in order to maintain the sample temperature. Testing with NICALON tows and mullite tubes demonstrated that the control scheme worked well for stationary and slowly moving ({lt}10mm/min) samples, but failed for fast moving samples. Difficulty with measuring sample temperatures was resolved by using a light sensor to measure the emitted light intensity and to relative degree of heating.
