Embodiment approach 1

[0017] Implementation 1: see figure 1 , figure 2 , an X-ray communication device based on a traveling wave tube, which includes: an electron gun 1 with a laminar flow electron beam 5, a microwave signal input window 2, a microwave signal attenuator 11 and a slow wave line structure 3 interacting with the electron beam, The magnetic focusing system 4 constraining the divergence of electrons in the slow wave line, the focusing pole 10 of the electron beam, and after the focusing pole 10, set the heavy metal target 7 made of heavy metal materials such as tungsten and molybdenum bombarded by the electron beam, and bombard the heavy metal with the electron beam Materials such as beryllium are arranged in the corresponding emission direction of the X-ray 8 generated behind the target to make an X-ray emission window 9 . The generation of electron beams in the electron gun can be, but not limited to, generated by cathodes that produce electron emission such as hot cathodes, cold ca...

Embodiment 2

[0019] Example 2: see image 3 , Figure 4 , on the basis of Embodiment 1, the focusing pole 10 structure of the electron beam at the outlet of the slow wave line structure is omitted, and the volume and weight of the tube are further reduced. This structure includes: an electron gun 1 that produces a laminar flow electron beam, microwave Signal input window 2, microwave signal 6 and electron injection 5 interacting slow wave line structure 3, magnetic focusing system 4 that constrains electron divergence in slow wave line, microwave signal attenuator 11, set at the exit end of slow wave line structure The heavy metal target 7 made of heavy metal materials such as tungsten and molybdenum bombarded by the electron beam, after the electron beam bombards the heavy metal target, the corresponding emission direction of the X-ray 8 is provided with materials such as beryllium to make the X-ray exit window 9 . The generation of electron beams in the electron gun can be, but not limi...

Abstract

The invention relates to a travelling wave tube based X-ray communication device, and belongs to the fields of electric vacuum devices and communication. In the process that an aerospace vehicle crosses a blackout zone of the aerosphere, the device modulates electron flow of a bombardment X-ray target in a travelling wave tube signal modulation manner, X ray signals are modulated and used for X ray communication, the problem that the blackout zone shields microwave signals is overcome, effective technical means is provided for communication in the blackout zone, and the device has significancein reducing the volume, weight and power consumption of the load.

Description

technical field [0001] The invention belongs to the field of electric vacuum devices, in particular to a communication electronic system in an aerospace vehicle which utilizes the working principle of a traveling wave tube to modulate X-rays for communication. Background technique [0002] Traveling wave tube is a vacuum electronic device, which is the core device of radar system, communication system, electronic countermeasure system, imaging system and other systems. Traveling wave tubes have excellent characteristics such as high frequency, high power, wide bandwidth, high efficiency, and radiation resistance. In aerospace vehicle systems such as satellites, spaceships, and strategic missiles, traveling wave tubes are widely used as communication signal amplifiers. [0003] However, when an aerospace vehicle passes through the atmosphere at a high speed, in a certain altitude area, the surface of the high-speed aircraft interacts with the atmosphere to form a plasma sheat...
