Collector surface for a microwave tube comprising a carbon-bonded carbon-fiber composite
Abstract
In a microwave tube, an improved collector surface coating comprises a porous carbon composite material, preferably a carbon-bonded carbon fiber composite having a bulk density less than about 2 g/cc. Installation of the coating is readily adaptable as part of the tube manufacturing process.
