ABSTRACT:
A novel window assembly with improved cooling capabilities for use in high power microwave tube and waveguide apparatus is disclosed. A septum with a circular central aperture is disposed between two parallel windows. Cooling fluid is circulated in from the periphery of one of said windows, flows toward the central region, through the aperture in the septum, and then out at the periphery of the second of said windows. This arrangement results in an increased cooling fluid velocity thereby increasing the cooling effectiveness of the window assembly. By adding surface features such as bumps, channels and the like to the septum, one can additionally increase local cooling fluid velocity in areas of the window assembly subject to greater localized heating. This is particularly useful in gyrotron tubes, where the energy impinging on the window surface is in the circular-electric-field mode and areas of the window surface are known to be subject to greater thermal stress.
