how does a cyclotron work?what can it be used to make?
can it be made as a school project?
Google is your friend. Learn to use it.
ok but there is no simplified example. this said i stumbled upon a beta tron and have absolutely no idea what it is about
Try this page about cyclotrons:
Start at the beginning. Tell us exactly where you first get stuck, and what you don't understand at that point, and maybe someone will help you get un-stuck. Then you can continue from that point and tell us where you next get stuck, etc.
thanks for the link however i did not understand how d charged particle/electron turned in a clockwise direction if a magnetic field is applied it shouldn't it decelerate and accelerate in the opposite direction ?
The magnetic force on a particle is always perpendicular to the particle's motion. Therefore it can only change the direction of motion, and not increase or decrease its speed.
and in particular, how you get a circular path:
the links were quite helpful however i read in Wikipedia that ''A betatron is a cyclotron to accelerate electrons The betatron is essentially a transformer with a torus-shaped vacuum tube as its secondary coil. An alternating current in the primary coils accelerates electrons in the vacuum around a circular path.The betatron was the first important machine for producing high energy electrons."
so how is it similar to a transformer?
could someone explain the design of the betatron in more detail?
The AC power generates a changing magnetic field. In a normal transformer this changing field causes an electric field in the secondary windings, which is how you step up or down the voltage and current in normal power lines. Instead of having a secondary winding, you insert the vacuum torus. The changing magnetic field accelerates the electrons since they are charged particles. I believe the changing magnetic field is able to accelerate the electrons because instead of the particle moving relative to the field, the field is the one "moving". This field accelerates the electrons away from it which happens to be in the direction of motion for the electrons. Someone correct me if I'm wrong.
On the picture in http://en.wikipedia.org/wiki/Betatron, I think that the white ring in the middle is the torus, with a connection pipe for the vacuum pump.
Such a betatron is similar of construction to the transformer type that is depicted and explained here:
The coils are wound around a metal piece in the centre, which is not visible on the picture.
More is explained here:
However, suddenly it strikes me that there is an important detail that has escaped me!
Probably they use a stainless steel torus and I think that if such a torus isn't insulated at one place, then it would function like a secondary winding - which would shield the magnetic induction inside. Does anyone here know about this issue? I didn't find a reference on it...
