The Global Scaling Principle (GSP) is formulated. GSP allows to build a 2,5-parametric class of klystrons fully equivalent to one given prototype. Klystrons included in the constructed class, may differ significantly on the operating frequency, power, voltage, according to the number of rays and other key parameters. At the same time all the physical processes in a class of devices are identical....
A new class of high-power klystrons, which use a dual frequency input and dual frequency bunching cavities, is proposed. This klystrons have both the efficiency about 90 % and the small bunching length. The global optimization procedure for the dual frequency klystron with the characteristics, suitable for modern colliders, was held. It was shown that the bunching process in such a klystron is very...
A new resonance device of the O-type, which was called resotrode with 2p-regeneration, is proposed. It contains 3-gaps input cavity with distance between the 1-st and the 3-ed gaps equals 2π. The device combines the advantages of the devices with modulated emission (IOT) and the advantages of the klystrons. Such a device has a high efficiency (90 % and greater), high gain (greater than 30 dB), small...
Using the mathematical model of electron beam transformation in a narrow tube developed by the authors and the KlypWin program suite, conditions for the maximal efficiency of decimeter-wave klystrons having from three to six amplification stages are simulated. Simulation is based on a real electron-optical system and real parameters of the cavities. It is shown that the maximal efficiency (across...
