慢波组件的散热能力是螺旋线行波管向高频、大功率、宽频带发展的主要障碍之一。本文就此问题提出了一种能获得散热能力高、高频损耗小的、简单可靠的工艺方法。还提出了散热能力的测量方法,并给出了测量结果。 (一)焊接工艺 1.慢波组件装配 试验慢波组件的尺寸如图1所示。首先将螺旋线镀上20—25μm厚的铜层。然后用真空蒸涂的方法在瓷杆上蒸涂一条钛层,并再在Ti层上蒸涂一层Ag- The heat dissipation capability of the slow-wave component is one of the major obstacles to the development of high-frequency, high-power and wide-band helix traveling wave tubes. In this paper, we propose a simple and reliable process method that can achieve high heat dissipation capacity and small high frequency loss. Also proposed cooling capacity measurement methods, and gives the measurement results. (A) of the welding process 1. Slow wave assembly assembly test Slow wave assembly size shown in Figure 1. The spiral is first plated with a 20-25 [mu] m thick layer of copper. Then a method of vacuum evaporation on the porcelain stem evaporated on a titanium layer, and then evaporated in the Ti layer of a layer of Ag-
