Hey. I am a freshman in high school, and iv'e been reading about building a cyclotron. I have the basic principles understood but can someone explain how exactly i would assemble on, and the mathematics behind it. ALso and information about how the fields interact would be phenomenal. I have...

I don't know what the speed of light c is doing in the Hamiltonian for the Landau quantization. The term doesn't have dimensions of momentum anymore. :confused: \hat{H}=\dfrac{\hat{p}^2_x}{2m}+\dfrac{1}{2m}\left(\hat{p}_y-\dfrac{q|\vec{B}|}{c}\hat{x}\right)^2 Any ideas? thanks.

Hi All, For a hydrogen atom in the field B, torque on the electron is \tau =\mu Bsin\theta =\omega_pJsin\theta => \omega_p=gqB/(2m) If we only consider orbital motion (ignore spin), then g=1. So \omega_p=qB/(2m). (It follows the steps from Feynman's lectures VII section 34-3) For a single...

I'm working on plans to build a small cyclotron as a DIY project (I'm a high school student). I've spent over a month researching a variety of sources (the rutgers cyclotron, etc.) and am working on some calculations, but I'm stuck with the mean free path equation. the equation I was using...

Does anybody have any tips/ advice on building a simple cyclotron? I read about Michio Kaku making an accelorater when he was a teen and was wondering how to make one.

what creates the magnetic field on a cyclotron? in all of the schematics I am looking at it just says "magnetic field points up" like it is extremely apparent as to what creates the magnetic field. I was thinking that a bunch of small diameter solenoids packed side by side would be the best way...

Hi, I am having trouble understanding the workings of a cyclotron. Supposing the typical design with two D shaped objects, changing potential differences between the D's, and a source of charges in the center, I can see that the particles would move in arcs (circles) at a constant energy. I...

This isn't exactly homework, but I felt that I had too much to ask that it wouldn't be right to put this in the regular section. Anyway, I've been reading the original paper on the design of a cyclotron (Lawrence & Livingstone) and there were two parts which didn't agree with what I knew... and...

Since the acceleration is transverse to the velocity, should we consider the transverse mass in the formula mv^2/r ie \gamma \frac{mv^2}{r} = qvB \implies \frac{v}{\sqrt{1-(v/c)^2}} = \frac{qBr}{m} ?

Can somebody explain the electron cyclotron frequency with minimum math please. thanks.

It seems not yet. http://aeroguy.snu.ac.kr/lab/research_cyclo_intro.htm

We know in a cyclotron motion, qvB=mv^2/R Can you please tell me if the charge requires energy as it moves... It is obvious that when it starts it requires energy provided by only the magnetic field. As it starts, it has constant velocity...no dissipation.Does it mean its energy remains...

Hi. I'm a college student, part of a group who will be doing a hands on study of particle physics next year. We plan to build a linear particle accelerator, after which we may go on to build a cyclotron. We'll be accelerating electrons to start off with. I would like to find out more about...

In a cyclotron, why do they not use electric fields to move them in circles?

I'm trying to build a small cyclotron and am thus searching for a magnet. I've been looking for a neodythium disc magnet that I could have cut in half to act as the two 'D' magnets in the cyclotron. The size of the magnet needs be somewhere around 12" in diameter but I can't seem to find...
