Magnetron, How does it work?

World War 2 was one of the most traumatic events in the history of the world, but on the other hand it also resulted in several inventions that have completely changed the world. One of the key inventions of this era was the cavity magnetron, which made radars super-efficient. Cavity magnetrons are also used in microwave ovens, where they are responsible for producing high powered microwaves. In this video we will explore the physics behind the cavity magnetron.

    It’s not bad for a simple overview, how exactly all this happens is rather more complex than it seems, quite a bit of pretty advanced physics going on... one thing left out more or less is the oscillating is in both the electric and magnetic feilds, it seems to focus mainly on the electric feild... still not bad for someone who just wants to know roughly how they work without actually knowing much of anything about how they work in reality...

    The key principle of the magnetron remained unmentioned. The electrons tramsmit their potential energy to the high-frequency electric field thus increasing its power. Without cavities and HF-field electrons move by trochoidal trajectories around the cathode and never reach the anode. But in presence of HF-field electrons interact with it, losing their speed and moving closer to anode. This leads to decreasing of electrons' potential energy (which is determined by their distance from the anode). This energy is transferred to the electromagnetic field.

The waves would have two dimensions . Place the rest of information in reply to further my understanding

As a result of being in (what was then) the longest school program in the Army, we were denied advancement in rank for nearly two years, still pulling KP while others were being promoted to cpl or sgt. It was this stupid situation that led to the Army losing the missile technology race and the formation of NASA.

    The short version: return wave has predictable frequency, big antenna with special shape points toward where reflection should be coming from, given speed of light thru air, measure time between outgoing pulse and incoming pulse to measure distance. Size of object corresponds to strength of reflected signal.

  • @busimagen

    adding to sunsor comment above : S send pulse, R = return pulse S______________R__ far S_____R___________ near Simple math on how long it takes to receive the return pulse will tell you distance. The pulse is directional, and if you rotate the sending antenna, the turning of the antenna is much much slower than the speed of light, so the return pulse will come back before the antenna has turned much (so, it is basically still pointing in the same direction). So, if you receive more than 1 return pulse, you have more than 1 contact in that direction. This makes it easy to use a cathode ray tube (the kind one would use for an old oscilloscope) to plot the signal. All the CRT needs to do is scan in the same direction that the antenna is pointing, and shoot electrons any time a return signal is detected, and the time it takes for the electron beam to make one scan to the edge of the screen removed the need to actually do any math (it just comes out as a result of the time it takes to trace/not-trace the line). If you do it digitally, though, then you actually have to do a bunch of processing before you can display anything. Using a CRT is thus a much much simpler process (just scan a line from center to edge in the same direction as the sending antenna, shoot electrons when there is a return signal received), adjust scan line speed to adjust zoom (slower scan line speed gives further out zoom; faster gives closer in zoom).

I presume it is almost the same principle as for ultrasonic sensor in Arduino, with a difference in speed, that is instead of the speed of sound 340 m/s one has speed of light 300 000 km/s. And as you pointed out, the speed of light/radio wave is way faster than the speed of rotating radar.

    An analogy of a magnetron is a whistle like that which a football referee would use. Think of the metal body of the whistle as a single tuned cavity (tuned to the pitch of the whistle). When you apply power to the cavity by blowing hard into the whistle, the cavity oscillates at its tuned pitch producing a loud noise very efficiently. The output (in this case noise) is transmitted via a port to the outside world. A magnetron is similarly a tuned cavity (actually a ring of cavities), and high voltage, high current provides the power. The magnetron output is a single frequency just like a whistle but at a very much higher pitch. That output is transmitted to the outside world by a waveguide (pipe). An electric whistle.

TV cathode ray tubes use the same principle but with electro magnets to bend the election beam to the correct part of the phosphor coated screen through a fine mesh mask. This uses very strong permanent magnets to cause the electrons to loop out then back in just like solar flares on the sun

    ​@@zealobiron I understand the issue was more economics for more resources (natural) and Germanification (some German work propaganda) of all of Europe and I guess the World since they were into Eugenics. Don't forget wasn't Hitler only... there were other Marxist with a range of Socialist Agendas with Franco, Mussolini and others. Jew's were the scapegoat and were also an issue with a cycle in basically jobs leaving the country and going east and even like now days to China... though I think then more like Eastern Europe and Middle East more-so... maybe Africa also. Figure Italy was developing Africa still, France was also and Spain and Portugal were still vested in South America. Technically, there are other Vacuum and Gas Tube "Tron" devices with the U.S., Great Britain, Germany and the Soviet Union leading developments regarding the specific ones. The Cavity Magnetron happened to be a scaled down system compared to the others since the others like cyclotrons and klystrons were huge. Eh, like most science, technology, math and engineering... there are subjects with subject matter experts and I'm sure there was a learning curve at first. Interesting how each side in WW2 would slowly advance their technologies so to not want the others to find out and use. I wonder what wasn't disclosed to this day? Solid State technology came out more at this era as well as more advanced logic methods also leading into transistor computers. kzread.info/dash/bejne/eX53qI-OlsTWpZs.html There are other episodes worth searching for or finding from your library and watching.

    Robert Buderi wrote a book about Radar, "The Invention That Won The War". It featured the magnetron which made it possible to output thousands of watts at more than a Gigahertz. Some Radars were at 10 GHz. The Radar I worked on put out 0.5 or 5 megawatts peak.

    As everything else from the English language media about Germany and WW I & II, ..."The Invention That Won The War"... is another baseless exaggeration. Radar had also been developed by the Germans, and the very high frequency type was much more precise that what the British could muster. Wikipedia is reasonably fair on this.

    Cellphone communications use microwaves, the only difference would be the amount of power. You really don't want to stand in front of a microwave beam of over 1000 watts of power, it wouldn't end well for you. Anything in the range of 300MHz and 300GHz are microwaves, under 300MHz is radio and above 300GHz is IR, visible light and all the way up to gamma rays. Just don't fuck around with microwave over magnetrons, or any other high power device lol.
