In response to the initial surprise and subsequent realisation of the importance of the Cavity Magnetron being sent (at a time when Whittle's prototype Jet engine was also sent) to the US "to see what they could come up with to do with it" the Americans responded with the comment that "The Cavity Magnetron was the single most important artefact ever to be put in an aircraft and sent across the Atlantic". The British had the need and the brains; the Americans had the time and the money - this IMO was the most important and (and beautiful) element of cooperation that arose because of WW2 and led to some of the massive technological advancements seen during this time.

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.

Thanks. Since detecting an object requires a return wave propagation from a reflected object it would be nice to hear how the return wave gets processed.
@_sunsor4 жыл бұрын
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.
@busimagen4 жыл бұрын
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).

Is there any way to produce microwaves at battery power (40-70volts) if a step up transformer is used (+ hf plasma), and without a vacuum? Or is a vacuum and high amperage required to produce any microwaves at all (even low energy ones)? From what I've researched there doesn't seem to be anything below the scale of microwave-oven magnetrons (which are huge, clunky and dangerous).

There were lots of different designs of Magnetron before Randell and Boot made this version in early 1940. The Soviet one was very low power (as was everybody else's (300-400 watts peak power)) and couldn't be used as a practical radar transmitter. In fact, the big problem was the Klystron produced more power without use of a huge magnet. The big difference between the Randell and Boot Magnetron and everybody else's was they were not radio engineers, but Physicists and unlike all the other Mangeton inventors who built their devices much like the Thermionic Valves of the day with thin walled Anodes encased in glass tubes, the British pair made the Anode the case of the Valve out of a block of copper. The British built their device before the Soviet one was patented. The other big problem with the other magnetrons were they didn't work for very long before the cathode burnt out. The problem was that the magnetic field forced electrons to slam back into the Cathode which over heated it. The French came up with a solution that overcame part of the problem, but it was a Brit at GEC who took the French solution, added an improvement of his own and embodied it into Randell and Boot's original design. This Magnetron could kick out 15 Kilowatts peak power and actually work for a reasonable life span and was the one given to the USA.

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

Two coils close together can transmit electricity via induction! Magnetic waves produce current when they cross a conductor.

I'm afraid there are NOT electrons really "propagating" or "mitigating" or leaving the conductor or filament itself If that was the case than we would need an infinity amount of electrons or simply wearing off the material in few seconds of on-state

There's a high voltage DC source connected between anode and cathode that supplies continuous flow of electrons to the cathode.

Radar was developed at MIT in a building, Building 20, that was originally built for the duration of the war, plus 6 months. But it still existed at MIT when I got there, in 1976, and I believe it was finally taken down in 1997. It was called the "MIT Radiation Laboratory": They were hiding one secret, radar, behind another secret, the atomic bomb.

Can I add more capacitors in parallel to allow a magnetron to run longer? If you notice microwaves "cook" with an on off on off. So 30 seconds would really be 15 seconds cook and my goal is to generate em waves in a constant blast. I'm guessing this is by design so as not to burn out the transformer or home wiring

During the war a test flight perfecting radar crashed killing all the crew running it. One of these was Alan Dower Blumlein who prior to the war was associated with audio recording and devised the method of stereophonic recording on the two sidewalls of a record groove. This crash was kept most secret for 6 months and a team under Bernard Lovell later of Jodrell bank radio telescope was sent to recover any remains of the radar.
