So I figured out the potential is: dV = (1/(4*Pi*Epsilon_0))*[λ dl/sqrt(z^2+a^2)] . From that expression: We can figure out that since its half a ring we have to integrate from 0 to pi*a, so we would get: V = (1/(4*Pi*Epsilon_0))*[λ {pi*a]/sqrt(z^2+a^2)] In that expression: a = sqrt(x^2+y^2)...

Amazing Answer! You really helped me a lot with those stadistics. The research I've made seems to tell that most people consider Vanderbilt a very clinical oriented program, and that the medical physicists that come out from this University are very good. It seems that most of them go for a...

Thank you very much Choppy! Great answer, it clarifies a lot for me.

Well I've already done the research, and got every program strenghts. I wanted a new perspective if you have one about any of these programs so I can have more information, If you don't have any opinion it's ok, but if you got, you are welcome to share it.

Good night to all, I would really appreciate if everyone could give me their opinions on: MS in Medical Physics in Duke University MS in Medical Physics in Columbia University MS in Medical Physics in Vanderbilt University MS in Medical Physics in Cleveland State University Ph.D in Radiological...

I understand the following image as follows: There is a build up region that varies with photons energy, the Dmax for 6 MV photons is around 1.5 cm. The build up region means that kerma > dose in that region, meaning that photons are creating electrons and when the Dmax is reached it is going...

Some time ago I made a modelling project and obtained a plot. Now, I want to remember what the transfer function was, as I want to try changing the parameters. The graph is the following: How can I obtain the transfer function? Thanks a lot

Hello all, I would like to know why an electron is accelerated in a linear accelerator because of the microwaves emitted by a magnetron?. Can someone tell me what are the relevant physics equations and what is the role of skin-effect here? Thanks a lot.

Guys, I'm keep searching for a WHO standard of Radon of Water in Bq/m3 but I can't find one. Can anyone help me find some references of maximun contamination level of Radon in Water? It may be EPA, or something else too. Thanks a lot

That would be all thanks, you are the best. Just to get all clear, could you explain why is the distance important here? Is it because the desaceleration/aceleration happen faster when distances are short so they have to be bigger? It doesn't matter one happens via bremstrahlung and the other...

Thanks a lot, where can i read about its deduction?

Thanks a lot, could you put the formula?

Ok so i think we can conclude is that the acceleration via potential difference is not enough for a good amount of x rays to produce so the bremshtrahlung or characteristic emision processes are the ones that matter for this fenomena, my last question would be why does the order of magnitute...

Totally awesome thanks, how can i do a fast estimation of why the accelaration due to the potential diference is insufficient?

Good morning all, I was just wondering the following question. When an electron is accelerated it emits electromagnetic radiation, depending on how much it is accelerated the energy varies so the frecuency does and the electromagnetic wave emitted would be of different colors or maybe even...
