The invention and increased popularity of RADAR increased the demand for devices which can produce microwave at shorter wavelengths. Czech physicist August Žáček and German physicist Erich Habann independently discovered that Magnetron could generate signals having frequencies of Microwave range. Hull developed a device almost like a Magnetron, but it had no intention to generate signals of microwave frequencies. The experiment was initiated to bypass the patent of ‘triode’ of Western’s Electric. In the United States, Albert Hull started working to control electrons’ motions using a magnetic field rather than using the conventional electrostatic field. He developed the mathematical model around the year 1912. Swiss physicist Heinrich Greinacher finds out the idea of electrons’ motion in the crossed electric and magnetic field from his own failed experiments of calculation of the mass of electrons. The Siemens Corporation developed the very first magnetron in the year 1910 with the guidance from scientist Hans Gerdien. A magnetron works only as an Oscillator but not an amplifier, but a Klystron (a Microwave Tube) can work as an amplifier and as an Oscillator.Ī typical Magnetron Microwave, Image Credit: HCRS Home Labor Page, Magnetron1, CC BY-SA 2.0 AT A Brief History of Magnetron Microwave There is a primary difference between a Magnetron and other types of Microwave Tubes. Magnetron tube consumes high-power, and its frequency depends on the physical dimension of the tubes’ cavities. Magnetron: Magnetron is a type of vacuum tube which generates signals of the microwave frequency range, with the help of interactions of a magnetic field and electron beams. Now, the definition of Magnetron is given as – They are the electron guns which produces linear beam tubes. Microwave Tubes: Microwave tubes are devices which generate microwaves. Before discussing magnetron and its related topics, let us find out some of the basic definitions.
