Full textA traveling-wave tube (TWT) is a device where an electron beam traveling along the axis of a helix interacts with the electromagnetic waves propagated by this helix. It is sensitive to many instabilities : oscillators (generating noise microwave), but also beam instabilities that generate a noise dissipation due to the interception of the beam by the helix. The aim of this thesis is to find a Hamiltonian formulation of the problem to allow more compact, more accurate and more complete approximate models. Having found one, we start to develop a numerical scheme containing our discrete model for the simulation of TOP. This discrete model has been developed to take into account the tapering sections, geometry changes and adaptations. The coupling with electrons involves simple functions of space, and the model takes space charge into account. Different methods of numerical integration are developed, of which we compare the efficiency. We compared the discrete model with various cold waves amplification models, especially with the model currently used at Thales for the design of their tubes ({texttt{MVTRAD}}). Moreover, we showed that two- or three-dimensional cold wave amplification models like {texttt{MVTRAD}} or {texttt{BWIS}} (which takes into account the backward waves) fail to respect the Maxwell-Faraday equation, contrary to ours. Finally we made a comparison between our circuit discrete model and the amplification model of cold waves in the case of a linear beam

Full textDuring these last forty years traveling Waves tubes did not stop developing directed by the increasing request of the new applications (High-speed Internet, TV HD). This increasing request in frequency and in power is translated by thermal heating problems. Indeed, the more the output power will be high, the more there will be of the dissipated power, with smaller and smaller size. This leads logically to bigger and bigger power densities. This produced heat must be evacuated by small contact areas, which depend strongly on the type of assembly. This thermal heating also involves changes of the mechanical behaviour. The principal point will be the study of the behaviour of the interfaces in traveling waves tubes. Thesis work, we study the thermal and mechanical interfaces produced during a hot shrinking. Goal of this work is to supply a numerical or analytical model of helix temperature determination with functioning. Considering the configurations of functioning (Vacuum, high-voltage, small dimension) a direct measure is not impossible. Nevertheless several indirect measure methods were investigated to find the most appropriate. This study concerns at first the transmissions lines then the collectors of TOPS. We realized an analytical thermal model allowing to identify quickly the thermal impedance of devices. A thermal contact resistance measurement and a metallographic cutting determining the contact areas feeds this model to give it a better precision. A 2D finite element allows us to identify an average pressure of contact to use the corresponding RTC. The thermal resistance, allows us to find the helix temperature by indicating the power dissipated in the line

Full textThis work deals with the development of a platform for theoretical and experimental investigations of microwave amplifiers devices of the type traveling-wave tube (TWT). The platform consists of a mathematical model and a test bench. The mathematical model describes the TWT as a transmission line coupled to a onedimensional electron beam, in which the AC and DC space charge forces are calculated self-consistently, eliminating the need for a separate calculation for the space charge reduction factor. The mathematical model gave rise to two codes for the simulation of TWTs. Both codes were validated against experimental and theoretical results available in the literature. The overall level of agreement between the present results and those from the reference was above 90%, which was considered satisfactory since not all input parameters were available in the reference. The test bench consists of a wideband TWT operating from 6.0 to 18 GHz and maximum saturated power around 55 dBm (316 W) at 13 GHz, a biasing circuit, and the instrumentation needed to perform the relevant measurements to the power amplifier. The TWT in question was characterized according to its mono-signal and multi-signal behavior. The gain and power curves were obtained as a function of the frequency using the beam voltage and the input power as parameters. The curves of power transfer, phase transfer and gain compression were obtained for selected frequencies along the operating band, again, using the beam voltage as a parameter. Furthermore, the production of third-order intermodulation products was measured at the 1 dB gain compression point over the band analyzed. A linearization test applying the signal injection technique, which was part of the initial work plan, presented inadequate performance due to problems in the linearizer circuit operation. These problems were analyzed and a guide to solve them was provided.
