关于将炭热解沉积在介质支撑棒上,以便在行波管中产生衰减方面的技术,几年来已有许多报道。有机化合物的热解机理及热解过程中的其它化学现象是众所周知的,本文不再重复。最近几年,在炭沉积及衰减器制造的暴力方法方面取得了一些进展。对这两种技术在提供复杂的,可重复生产的衰减形状的现有能力方面进行了讨论。在改进炭涂层的稳定性及在适宜的基底上得到锥形形状方面作了巨大的努力。近几年来,这些技术已很有把握地用于实践,这件事就使管子设计人员在减小行波管长度及得到更复杂的性能参数方面有更大的回旋余地。
There have been many reports on the technique of pyrolytically depositing carbon on dielectric support rods in order to produce attenuation in traveling-wave tubes. The pyrolysis mechanism of organic compounds and other chemical phenomena during pyrolysis are well known and will not be repeated here. In recent years, some progress has been made in the area of violence against carbon deposition and attenuator manufacturing. Both technologies are discussed in terms of the existing capabilities of providing complex, repeatable, attenuated shapes. Great efforts have been made to improve the stability of the carbon coating and obtain a conical shape on a suitable substrate. In recent years, these technologies have been used with great certainty in practice, giving the pipe designer greater latitude in reducing the traveling wave tube length and obtaining more complex performance parameters.
