Title:
セラミックマイクロ波ウィンドウ
Document Type and Number:
Japanese Patent JP2004521543
Kind Code:
A
Abstract:
The invention relates to microwave windows used for providing a vacuum seal and transmitting the electromagnetic energy output by a high-power microwave tube. The window comprises a dielectric disk and a prestressing ring, placed around the periphery of the disk, exerts, when at rest, a radial compressive stress all around the disk. In practice, the disk is brazed to the inside of a metal skirt, and the prestressing ring is an annular portion of a holder used for rigidly fastening the microwave window to an output of the microwave tube. The annular portion has an increased thickness and bears locally on the skirt around the disk. The disk may be made of alumina, the metal skirt made of copper, and the holder made of stainless steel. The resistance of the window to thermal stresses is considerably improved thereby.
