Some help with calculations please :) So my friend Ryan is building a home made cyclotron particle accelerator. I'm rather interested in building one of my own, but fear I lack the technical know-how and mathematical practice to do so just yet. I asked him how he is building it(on facebook, heh) and he replied as such: "well first off I am modeling it off of a cyclotron .... its taking two D shaped plates and having an alternating current go from each plate what i then do is calculate the frequency of a particle * ion* under the influence of a magnetic field... which is created between these two slolinoids they are producing about a 4 or 5 Tesla field... try to calculate is with these parametiers and see what you get with n( turns) = 3400, I = 5, L=.1(meters) with a magnetic core of iron with a K of 200 .... tell me what you get and I will explain more lol we can have a lil fun exciting challenge with this lol ttyl im going to eat dinner" I feel his response is slightly unclear, but I don't care to ask him to elaborate on facebook. Would somebody help me interpret the symbols and units and brief me on any formulas I may need to calculate the frequency of the ion? That would be a big push in the right direction.
