Very cool. The narrator kept answering the questions I had as I had them. "OK but where is the RF amplification coming from?" "We must now consider how the outgoing signal is stronger than the input." Yes!
Great video. May be old and on film, but it's very clear! Never understood the cavity resonance, however the graphic of the cap and inductor was fantastic. Thanks for posting.
What are great video! It just goes to show, you don't need flashy animations or graphics just a proper understanding and good language. At the start of the vid I was like "oh god 15mins!, but that time went by so quick, I was hooked!"
Then again this would be considered "flashy animation" by those who can learn by reading a well written text describing, a well drawn static illustration. Then again I may never understand some who wine about how old school is somehown better that modern technics used to accomplish the same thing. I'm puzzled why the whiners are using a computer and the web. In the event old school is so great, shouldn't the whiners be mail ordering the film (silent), and using a projector to view the film?
@@1010tesla i am an engineering physics undergrad living in New Delhi, India, and i have the subject microwave engineering this semester. So yeah i study klystrons
Even we are in an advanced age their teaching methods were thousands time more better than us. That's why they were the founder of our modern age. well done💯
I beg you to please add more such videos on telecommunication and microwave engineering...This was so much fun and so easy to understand. Nothing can beat an explanation like this. Totally loved it!!
One of the best explained video so far. What I have seen tough, in early times where the animation technology was quite inchoate shows us the highest teaching material effect. That is crazy. We need more video like these.
The explanation couldn't be any better! I wish if you could upload the explanations of all the rest of the microwave devices if available. Thank you for this. It helped a lot!
The most clear explanation and illustration of the main concepts of a Klystron. Really would like to have an equivalent video of how the Magnetron works !
Thanks for upload that! I really would like to have access to that film 35 years ago when graduating in Electronic Engineering... I had a very difficult time to understand then resonating cavities! :-)
really best ever explaination in the youtube. there is no video like this. very very much helpfull thank you soo sooo soooo much for this video explaination on youtube.
While at a technical school I was taught microwave tubes and microwave amplification but I couldn't understand then. Today my interest is only to get a qualitative understanding about the types of Klystrons so that I will be able to do some exercises later. You have struck gold in those videos, thank you for sharing and keep posting.
Here comes 1 more like from Indian........Man you have done a great job by making this video.....thanks!!!! Really helped me a lot.......And please add more videos to the playlist.
Thanks for commenting. Do you work with or study Klystrons? klystron application is pretty limited so I am always curious what brings people to this video.
@@1010tesla Engineering studies bring most of us here. I wonder how smart the old inventors(late 1800s to mid 1900s) were, how can they even imagine such a thing....fascinating.
If we got like this kind of explanation for every thing means it is very easy to understand.This is THE BEST explanation about klystron. Thank U for this video. Do you have any videos related to modes of operation (TE, TM, TEM)? if you have means upload it too it'll be useful us.
thank u a great thank you to sir . seriously a very helpfll video to learn from why college teacher make us study from these type of tutorials again thanks a lot sir
So complicated, but so simple at the same time. The simple part involved firing off electrons from a cathode, and the cavity resonator - both very simple concepts (a cavity resonator is just like an LC tank circuit, basically). The complexity was in how those two simple electrical actions were combined, and that the result was amplifying an input RF wave.
That thing is ingenious. Thanks for posting this video, I always wanted to know how these work. As a tl;dr: The amplification works because the input signal is only used to modulate an existing electron beam while the output signal uses most of its kinetic energy, aye?
@@1010tesla I do not. I just have a weak spot for all things physics. If those things involve electric fields, accelerated electrons and radio signals, I get a little hard.
For the coupling of the coaxial cable to the first or second resonator is the center connector terminated to the surface of the cavity? or is it air coupled
@@1010tesla Yes. I am an electronic engineer and physicist. Currently I work in a startup where we develop automatic frequency control systems for magnetrons and klystrons used to provide RF to linear accelerators. And you?
something i've noticed is old school videos like this from the 50's, 40's and even 30's are the best for education. they start from simple principles, don't assume you know things already and only show you what is important. it's a skill that I think has been lost somewhat
so the feed line into the first resonator is a 1/4 wave antenna sw, I understand scientific extension, is a fifth or a 9th wave antenna strumm a higher harmonic
I think it's awesome how such an old educational video can be just as good (and even better) than a lot of contemporary videos. Things were legit back in the day.
@@1010teslaNo problem, and I've never actually worked with a klystron. I'm just a bit of a math and science enthusiast and tutor some kids, and often times go on TH-cam to explore a bit. How about yourself? Have you ever worked with one in-person?
@@1010tesla from the early beginning..at first you show the original one then explain the concept behind it. Thanks again I am studying this in college..one more request please upload other electronics related videos
Sir can you give me suggestion how did you build your thinking and concepts.........please sir guide me . I will be ever thankful to you sir..... I will be waiting for your response.🙏
Uhm starting at 5:12 you have magnetic field vs. current following a "left-hand rule", whereas we all now that it follows the right hand rule. Thoughts?
+rai ZOR Whoa. So the right hand rule which is taught in introductory physics is used for hole current, not electron current? That is peculiar, since holes were not even introduced as a concept in that class.....
ilikeeggs216 really? The fact that conventional current & electrons travels in opposite directions is one of the first things you learn when studying electricity, we learnt it in high school.
@@1010teslaOh, I am an electronics and telecommunication engineering student and have to study this topic under the subject 'Microwave and RF devices'.
it's got 2 be from the 30's 0r 40's!! it's historic!! that was back when this stuff rockNroll....nice video!! I hope it inspires, some young engineer!!
Very interesting technology!! Why is it only being used in sending signal? It is power amplification utilizing resonance frequency. The higher the frequency, the higher the accumulated electrons at the collector? Small input power at the resonance cavities can produce massive electrons accumulation at the collector. Why we do not use technology like this in power generators to suck up electrons from the ground?
Thanks again for your articulate video. Actually I am a Medical Physicist and I have to know whole stuff respect to Linac. The video guide me perfectly through how the klystron act as a fundamental part in Linac.
Best explaination of a Klystron I've found on youtube
Definitely !

there's a lot of old school videos like this on youtube. they really knew how to explain something back then
It is so well explained as if the creator of klystron amplifier himself explained the working.

my teacher wasted 3 lectures for klystron amplifier but I failed to get such a easy thing . Sir you are amazing need a teacher like you
this is a video from 1950 haha
These older videos are splendid learning aids.
Great job Sir! You explained it patiently and conceptually.
Thank you a lot for uploading this video. Klystron is now understood!Very well explained with the animations! I want more videos like this!!
The most clear explanation and illustration of the main concepts of a Klystron. Really would like to have an equivalent video of how the Magnetron works !
Almost seems that the magnetron is a klystron folded into a circle, with the magnet steering the electrons round
