Magnetron radiation
WebThe name Radiation Laboratory, or "Rad Lab," was chosen to be intentionally deceptive, creating the perception to those on the outside that the laboratory was working on nuclear physics, a discipline that was seen as too immature to have an impact on the war effort. During the fall of 1940, the Rad Lab sprang to life on the MIT campus, and by ... WebIf the hot plasma happens to be magnetized (like the tokamak/pinch plasma, X-ray binary stars, etc.), then the electrons also emit cyclotron radiation (also called magnetic Bremsstrahlung) due to their gyration around the magnetic lines of force. The acceleration is due to the Lorentz force acting on the moving electrons.

Synchrotron radiation (also known as magnetobremsstrahlung radiation) is the electromagnetic radiation emitted when relativistic charged particles are subject to an acceleration perpendicular to their velocity (a ⊥ v). It is produced artificially in some types of particle accelerators, or naturally by fast electrons moving through magnetic fields. The radiation produced in this way has a characteristic polariz… WebAug 28, 2009 · A magnetron's job is to generate fairly short radio waves.

The magnetron is a self-oscillating device requiring no external elements other than a power supply. A well-defined threshold anode voltage must be applied before oscillation will build up; this voltage is a function of the dimensions of the resonant cavity, and the applied magnetic field. See more The cavity magnetron is a high-power vacuum tube used in early radar systems and currently in microwave ovens and linear particle accelerators. It generates microwaves using the interaction of a stream of See more All cavity magnetrons consist of a heated cylindrical cathode at a high (continuous or pulsed) negative potential created by a high-voltage, direct … See more Radar In a radar set, the magnetron's waveguide is connected to an antenna. The magnetron is operated with very short pulses of applied voltage, resulting in a short pulse of high-power microwave energy being … See more • Crossed-field amplifier • Yoji Ito, a Japanese military electronics expert who helped create Japan's first cavity magnetron devices See more Conventional tube design In a conventional electron tube (vacuum tube), electrons are emitted from a negatively charged, … See more In 1910 Hans Gerdien (1877–1951) of the Siemens Corporation invented a magnetron.
