- Cyclotron- Principle, Construction & Working
Cyclotron
Cyclotron is a device used to accelerate charged particles to high energies. It was devised by Lawrence
Principle
Cyclotron works on the principle that a charged particle moving normal to a magnetic field experiences magnetic lorentz force due to which the particle moves in a circular path.
Working:
When a positive ion of charge q and mass m is emitted from the source, it is accelerated towards the Dee having a negative potential at that instant of time. Due to the normal magnetic field, the ion experiences magnetic lorentz force and moves in a circular path. By the time the ion arrives at the gap between the Dees, the polarity of the Dees gets reversed. Hence the particle is once again accelerated and moves into the other Dee with a greater velocity along a circle of greater radius. Thus the particle moves in a spiral path of increasing radius . The particle with high energy is now allowed to hit the target T.

Sir, a fantastic attempt to clear up all the doubts in our mind. A bunch of hearty thanks!
😊😊😊
Yes really absolutely nice video
R u from MLZS
True

I am basically a visual learner...this video was really helpful for me ....It cleared all my doubts regarding the working of a cyclotron...Thank you so much sir....
Y'all class 9 students should stop commenting that "velocity has changed speed remains constant" . Everyone knows that and that part is understood.
😂
These kids consider themselves as big scientists after knowing this🤣
Ngl that was a major mistake in this lecture, and many can definitely get confused beacuse it was said several times
Otherwise this lecture was so good 😃

Just one question, which software did you use to create the animation ?
Nice and helpful video btw, keep up the good work !!
blender software
This video couldn't possibly be better Imy opinion thank-you sooooo much!
very well explained and even very minute details have been taken into notice .
Great job Sir 👍
ur the kid from dairy of a wimpy kid arent you
Some mistakes are there in video
@@kristianbennett9149 'diary'
@@ajitkher5559 what are those mistakes?
sir velocity is not constant inside the d, magnitude of that velocity remains the same not the direction.
yaa bro speed is same
Agreed
Yeah, right!!!
He should have probably used the word speed instead of velocity
no problem, everyone know that😂
my scl took me half an hour to explain this concept i cant understand anything but this man explained it to me for 6 min ii can understand everything............. thankyou so much sir
this was way too mind blowing . thanku so much for explaining it with such clarity and sharing ur deep understanding of the concept in the best way possible.
I had never seen before..... this much clearity in any concepts🙏❤️....a lot of respect sir❤️🙏....keep making such vedios on more concepts.....you really done a fantastic job🙏❤️......thanks for clearing my doubt as much as i need❤️🙏
Thank you very much for your perfect scientific explaination.
Well whatever may be it was explained neatly and clearly
I must appreciate your help 🙇♀️🙏🤗
Excellent
Tis video brings out the clarity n makes the topic simpler . thanks
THANK U SO MUCH!! The video was very helpful and concept was explained really well
What a wonderful explanation 👌 very much helpful
When will i read about these subjests .i mean in which class. This is very interesting
Class 12th syllabus of cbse
You are in class 7/8 right?
You can do it now, it's not hard. But learn Electromagnetism first. You can watch IIT-JEE lectures available on TH-cam for class 12 . First do that then learn this, otherwise learning only this is wastage of time.
@@studiousboy644 i am 11th

Beautiful explanation..... I like it.... It is too much helpful for me.... Thank you
the video lecture was excellent but can you please tell me how can we decide the place of hole so that the particle leave from it
It's very useful thank you sir 🙏🏻😊🙏
this is so helpful!!!!!!!!! thankyou!
Nice explanation on this topic in you tube history ever
Thank you it seems to be very helpful
Finally I understood it...💔..thanku sir for this wonderful video.
Thank you! Amazing explanation and video.
Was this animated in Maya or Blender?
Hey Naruto
This work is real act of hard work and ability to make a complicated topic simple.
Pls ... make more videos sir !

Bravo sir....never ever have heard such a great explination....plxx keep uploading more videos
"frequency of cyclotron is independent of speed of the particle, this fact is exploited in cyclotron to accelerate the particle....." I didn't understand this sentence
please anyone explain this clearly...
Frequency is 1/T so the time period is constant. so for each complete circuit of the cyclotron. The speed increase is balanced out by the increase of the radius.
Timeperiod of circular motion of a charge in a magnetic field is given by 2piem/qB...in this you can see there in no v(speed of particle)...and frequency is 1/T so... this is why he said it is not dependent on velocity of charge
Excellent explanation!
Sir bhot hi jyada accha samjhate ho superrrrrrr
4:38 it should be "magnetic field cannot change the speed" rather than the "velocity"

Yess..momentum and speed cant be changed
@@raghavrana9760 speed and kinetic energy cannot be changed. Velocity and momentum can be changed(direction).
@@tejashwiniramesh7173tangential acc. Is zero so speed remains constant and velocity changes😊
@@raghavrana9760 No . Momentum is a vector. It'll change
Concisely, but well precisely explained, thank you Sir, 😊
Better explaination.... Good 😉😊😉
You are awasome sir, i am thakful to you for such explanation
There is a little mistake in the explanation... when the particle enters the cylindrical D , there is a change in velocity.. magnetic field can change the velocity.. what does not change is the speed of the charged particle...
Mike De Moose no ... the spd of d charge change .... coz the particle have to cmplt d semicircle within the fixed tym ...
Yeah! You are right. He made a mistake.
U mean angular velocity remains constant?
Mike De Moose You took too much into consideration.
For those who didn't understand - the velocity depends upon the direction also. As the direction of the particle changes the velocity also changes but the magnitude of velocity or the speed does not change.
JAmes BoNd 007 .well done..spotted the right mistake which wasn't a big mistake.ur ryt...mag of velocity doesn't change but it's direction does.
Nice explanation . I got clear idea through daigramatic view .
Thank you!
Outstanding work and explanation thanks sir buy
thanks from France :)
just superb ,excellent ,if we have been taught like this sice childhood ,so surly we would have scientists now ,stay blessed sir ,thanks
Simple and perfect
Awesome explanation sir... clear now
sir, how you do these animation..
thanks a lot sir....
keep teaching us with such great animations...
you miss one thing how do machine know exacly when to change polarity
It doesn't know. It is correctly timed by the operators such that it changes polarity every t/2 seconds.
Very successful way of teaching of such machine 🙏
Thank you for simpl tric
Thank you sir...I try many times to understand cyclotron...but only from video I understand it 100% clearity ✌️✌️✌️
please make video on ac generator!!
Very nice 3D animation. Greatly helps in understanding and visualizing the concept.
Before exam🙃🤕
Which exam did you write?
Fake exam for likes@@jaybeezw
@@MrGaneshsr hypocrite 😹
@@jaybeezw semester
a simple explanation. thank you very much sir
In last step your electric field was from negative to positive
You are right
Hmmm 👍
Right mam
awesome sir jii its really great awesone
if dees are open to get the electron inside then how electric field can be 0 inside deese......
praveen dwivedi dees are made up of hollow sphere and outer hollow sphere there is electric field but inside dees there is no electric field
Since dees r metallic conductors , charges reside on their surface not inside...So there is no electric field inside .
Hope u get tat ..😃
Totally clear concept sir watching your video from Bangladesh
perfect!! Thanx alot
Sir so clear and amazing explanation 😊awesome sir
just question . can man build a cyclotron able to reach escape velocity for radioactive waste.
to the sun
the escape velocity to sun from earths orbit is 42.127 km/s....
the only limitation this cyclotron faces is that if velocity crosses speed of light then the frequency becomes zero more like placing a pendulum in the middle of the earth it wont oscillate
this can be followed up by einstein special theory of relativity ...
and yep you cant oscillate neutral species and only charged species can be accelerated and also using an electron is not preffered cos its mass is not effecient to initiate an acceleration and get a massive velocity out of the cyclotron.....
so basically what am saying yes it can reach escape velocity but what you tend to do with it is not practical
its like launching nuclear waste to earth atmosphee
re
lots of variables and lots of stuff can go wrong and the high enrgy radiowaste can even bombard the atoms in our atmosphere on its journey to the space.....dude cmon think about it...seriously
Simply we can't accelerate that much mass to such a high speed.It will take lots of energy
@@azzyboii830 oh very nice so you basically talking about the most basic principle of theory of relativity that is velocity increases mass so exactly you are wrong indirectly because any charge particle (except electron and other which have less than gram mass) can travel at speed of light such that you should just have adjust the duration of time to radiate energy from any charge it will behave like infinite mass.....you should lot to learn about special relativity
Just take it seriously you are right but didn't understand simple concept
Not explaining about cyclotron just want to clear concepts
I write only few points
Also not taking about electron because it is not compatible unit against speed of light very neglect mass it has
@@metawhirl4609 basically you're not getting at any point here
Don't waste your time yoooo➡️➡️➡️
@@dncmi1436 you are absolutely right
Oh my god thankyou so much. I was struggling to understand this. For some reason i couldn't imagine this
Be accurate, speed cannot be changed , velocity can be.
Sir, you explanation is awesome.... Accidentally I find your channel and it helps me lot..
good one guyz
Hello sir,
Ur explanation was great sir and the cancept was made clear .
Thank you
i am so happy with your video
Great animation... With great explaination😇👍🙏
4:40
You should have said that magnetic field cannot change the speed
For Direction?
Amazing Sir! Thank you so much!
Why not electron is used??
Maybe because of its extremely less mass, it may not be useful in nuclear fission. I am not sure though.
@@anmolagrawal5358 is right. The main use of this machine when it was first in invinted before the Manhattan project. The main purpose of it was to accelerate a larger particle so that it would have enough energy to break up a radioactive element setting a chain reaction. The electron would even to small to effect the large heavy radioactive metal
@@codyburkholder7397 Um you partly wrong sir. You are right about electrons not being used due to EXTREMELY SCARCE MASS but sir the penetration power of an electron is FAR FAR greater than a PROTON or a NEUTRON. The actual reason is that the electron would be accelerated to such high velocities that it would become out of phase with the oscillating field & it is EXTREMELY TOUGH to perceive its curvature at such high velocities so the desired effect of cyclotron wouldn't be achieved. :D
Because on high velocity the mass of electron changes
@@ceramicblocks can u clear this point a lil bit ?
sir by listening to you i will not learn only your teaching and notes is enough
keep it up
thanks sir
big up ,keep this up
Question:
At moment 3:26
Why does the video show the effect of the NORTH magnetic field that comes from the bottom electromagnet ?
What is the job of the top electromagnet ?
Very great video.
After all that IT HITS THE TARGET ?
I mean what kind of target ?
Can't we just use a pistol or something ?
NOT BEING SaRcAsTiC
the target is generally a small particle more than a trillion times smaller than a bullet
@@xGensai thank you
Cyclotron is kind of a particle collider. It collides charged particles with other small particles. This has a huge apply in nuclear and atomic physics experiments. Many sub atomic particles were discovered using particle colliders (the latest one being in 2013, which is called Higgs boson, or 'the god particle'. It was discovered using 'large hadron collider' at CERN). As far as 25 people have won noble prize just by discovering new particles using cyclotron...
Thank you soo much..! It was simply innovative, the best video ever seen...for the explanation of a cyclotron...please update your videos for moving coil galvanometer also..!
Excellent explanation 👍
Sir,, very clear and fabulous introduction of cyclotron machine... thank you soo much.. I understanded everything very clearly...
