Liquid cooled band edge oscillation prevention for a twt

阅读：720发布：2022-12-03

专利汇可以提供Liquid cooled band edge oscillation prevention for a twt专利检索，专利查询，专利分析的服务。并且A longitudinally extending liquid cooled attenuator is disposed proximate to and externally of a traveling wave tube coupled cavity slow-wave structure. The attenuator may be a hollow dielectric tube filled with a lossy fluid or a hollow dielectric tube with a lossy solid which is cooled by a moving fluid or a tubular ceramic rod disposed coaxially about an electrically conductive rod. This device lends itself well to the prevention of band-edge oscillations in the coupled cavity traveling wave tube.，下面是Liquid cooled band edge oscillation prevention for a twt专利的具体信息内容。

权利要求

1. In a traveling wave tube having means for providing a stream of electrons along a predetermined path and means for propagating electromagnetic wave energy comprising means defining a plurality of intercoupled interaction cavities in a manner so that an interaction takes place with the stream of electrons, the improvement comprising: means for preventing band edge oscillations including a plurality of irises coupled to the auxiliary cavities disposed proximate and externally to said predetermined path such that the longitudinal axis of said means for preventing the band edge oscillations is parallel to said predetermined path means for cooling the auxiliary cavities; and means for isolating the cooling means from the auxiliary cavities.

2. The device as claimed in claim 1 wherein said cooling means includes an elongated, electrically non-conductive tube adapted to receive fluid.

3. The device as claimed in claim 2 wherein said oscillation preventing means includes an elongated, electrically conductive tube disposed coaxially within said electrically non-conductive tube.

4. The device as claimed in claim 3 wherein the outer diameter of the electrically conductive tube is equal to the inner diameter of the electrically non-conductive whereby the tubes are in contact with each other.

5. The device as claimed in claim 3 wherein the outer diameter of the electrically conductive tube is smaller than the inner diameter of the electrically non-conductive tube whereby fluid can flow between the tubes.

6. The device as claimed in claim 2 wherein said oscillation preventing means includes an elongated, high loss tube disposed coaxially within said electrically non-conductive tube.

7. The device as claimed in claim 6 wherein said oscillation preventing means further includes an electrically conductive rod disposed coaxially within said high loss tube.

8. The device as claimed in claim 2 wherein: said non-conductive tube is comprised of a low loss material; and the fluid is a lossy fluid.
