Also I don't know if you or someone else does your white board but it is very well done in addition to the lecture. Clear handwriting, and the shape of the half-circles are perfect. Absolutely no flaw I'm just impressed.
Wonderful lecture. Extremely lucid explanation and stellar presentation. I am understanding physics mainly due to your videos. Keep it up - I know these videos are a LOT of work, but hundreds of thousands of people (like me ) are benefiting tremendously!
I appreciate these videos so much thank you. You are so good at conveying information in a way that is understandable and easily graspable. So again I thank you because these videos are very unique! Not many on youtube like this, it seems like there are none at all. I hope you keep at it these are amazing!
Hey Sierra! Thank you for your kind words. I've worked hard to get the whiteboard and everything else as clear as possible. So its good to hear that people like you are noticing and benefiting! :)
,This is such an incredible lecture! Sir, you are one of the best teacher I have seen in my life! Thank you for all of your videos and for the amazing service you do by putting them online, making education accessible.
Brilliant! Thank you so much! You are considerably better at teaching than my teachers - you convey information in such a concise, clear and understandable way :)
Has anyone ever told you how much you look and sound like Leonardo Dicaprio?? Appreciate the videos! Been looking all over the UA-cam for nice clear concise videos on these subjects - particularly particle physics. Thanks man!!
Actually yes! lol funny to hear you say that though. Glad to here it! Make sure to check out my site, you'll find a chapter on particle physics in the modern physics section. I did not go too much into the details of it, but I do have the general concepts and ideas!
Walter.Lewin of the MIT now retired says Any teacher who makes Physics not interesting is a bad teacher Any teacher who makes Physics interesting especially to poor meritorious who could not afford these very costly coaching centres full of mistakes and fanciful explanations of Physics Is to me The Best Teacher Thank you In my 38 years of teaching Physics in college I have not found a teacher with every day example with enthusiasm trying to convince students this way on cyclotron which many students are often heard to commit to memory from bazar. Notes very costly
i m so lucky to find u on UA-cam n sir u r jusss awesome n ur teaching style is too good to understand easily after watching ur videos i know everything basically n i get a lot of help during examination.. thanks a lot sir☺☺☺
Another fantastic video as always, thank you AK Lectures. Your biology lectures are also world class as far as I'm concerned :) The thing I'm unsure about on this video is: shouldn't we be using "left hand rule" instead of right? I'm probably wrong but I just thought to mention. Thanks again!
I take this oppotunity to thank the professor for the down to earth explanation of the cyclotron touching circular motion of heavy.particle not electron remember children Lorentz equation Dees explanation vacuum Oh in time of OnLine teaching if children could be taught this way those poor who never could afford to be coached by these mushroom coaching centres very costly would be greatly benefited Thank you sir Keep the good lecture heartening Let science teaching be thiis way to make Physics interesting and not shy away our poor meritorious
Really nice and clear presentation. However, it is not clear to me why an AC source is needed. Since the particle is spiraling out counterclockwise about a central region, we could have a constant voltage in the top half and same, but opposite, voltage in the bottom half of the cyclotron. What am I missing? Thank you!
I wonder, as the speed increases, doesn't it take the particle less time to transverse the region with the electric field? The distance between the two electrodes is the same, the velocity is higher at each half-turn, hence it takes less time. Does this mean that the true time it takes for a full turn, it gets smaller and smaller at each turn. The the frequency should be corrected accordingly(?)
Great explanation! One question though: What would happen if the radius of both the semi circular chambers becomes equal? Would it perpetually keep rotating between the chambers or escape tangentially( if so, the from which chamber?)?
I'm curious....can the accelerated particle be ejected from the cyclotron in the form of a beam? What is done with the output particles besides a target. If a conductive line is attached to the target, can we use the accelerated particles as a current? Thanks
The entire collection of particles is ejected from the accelerator linearly, so yes, it would be in the format of a beam - although to nitpick your question, a single particle is never a beam, only a collection of particles can be a beam. You wouldn't want to use an accelerated particle to generate a current. One, it doesn't really make sense, you don't need it to be accelerated to do that, and two, between the ion source, the electromagnets, and the oscillating field, you'd expend a great deal more energy than a beam of protons could induce current in a target.
The two semicircles are charged electrically by the oscillator. Thus, you have a positively charged and negatively charged semi-circle (D) at any given moment. The accelerated particle, typically a proton (+ charge) is shielded from electric fields while it is inside one of the hollow Ds. While it passed between them, however, it is no longer shielded. While in the gap between the two Ds, it will be attracted electrically to the negative D, and repelled by the positive D. Thus, while in the gap between Ds, it will accelerate linearly towards the opposite D. Once it enters the D the electric field no longer acts upon the particle and it stops accelerating. Due to the influence of the polar magnetic force acting upon it (and the absence of the electric force) the particle is spun around the pole of the magnetic field towards the gap again, where the voltage has been oscillated to the opposite charge it was on the last pass, and thus it is attracted to the opposite D again and again.

i wish i had found your channel in my AS,would have made my life easier. Excellent lectures, beautiful and clear handwriting.
love from Bangladesh
your lecture really helped me . it was nice video. thank you sir

Awesome explanation...👍

GREAT EXPLANATION.!THANK YOU SO MUCH.IT WAS REALLY HELPFUL
i m so lucky to find u on UA-cam n sir u r jusss awesome n ur teaching style is too good to understand easily after watching ur videos i know everything basically n i get a lot of help during examination..
thanks a lot sir☺☺☺
should't the frecuency of the cyclotron be 0.5 the frequency of the particle as it travels only half circle?
I'm previlaged to see you on the UA-cam thank you,the concepts are clear.
absolutely flawless and simple
Superb the concept is taught well
what an explanation! thank you sir!
thanks a lot , your illustration is simple and amazing

WOW, Beautiful Explanation.

Thanks a lot for you very interesting lecture

Amazing !
Very impressive

Prayush Dawda no
the radius of both the chambers are same
and it has all the same concept as in the video
great 😙😙tutorial should be of this kind love yaeh.!
I'm curious....can the accelerated particle be ejected from the cyclotron in the form of a beam? What is done with the output particles besides a target. If a conductive line is attached to the target, can we use the accelerated particles as a current? Thanks

amazing video
is cyclotrone and particle accelerator the same ? 😕
one doubt
what exactly causes the greater velocity after every rotation
The two semicircles are charged electrically by the oscillator. Thus, you have a positively charged and negatively charged semi-circle (D) at any given moment.
The accelerated particle, typically a proton (+ charge) is shielded from electric fields while it is inside one of the hollow Ds. While it passed between them, however, it is no longer shielded. While in the gap between the two Ds, it will be attracted electrically to the negative D, and repelled by the positive D. Thus, while in the gap between Ds, it will accelerate linearly towards the opposite D.
Once it enters the D the electric field no longer acts upon the particle and it stops accelerating. Due to the influence of the polar magnetic force acting upon it (and the absence of the electric force) the particle is spun around the pole of the magnetic field towards the gap again, where the voltage has been oscillated to the opposite charge it was on the last pass, and thus it is attracted to the opposite D again and again.
