    Cyclotron exit energy

    Well, thanks a lot! i'm pretty excited too. actually, i'm on a training right now at an already set up facility so i can see how things roll and then i'll go back to where i live so i can use a recently set up cyclotron there. all i know about the optics of the beam is that it's a negative ion...

    Cyclotron exit energy

    btw, i'm going to check with the company that sold the equipment to see if they got more info on the beam optics they use. if i get to see anything interesting i'll post it here. thanks a lot btw for the MAD link and the book, definitively going to check them. Great resources for this new job :D

    Cyclotron exit energy

    yeah, that's what i thought too.. but that spread should be fairly constant (that's what i meant, sorry for being vague)

    Cyclotron exit energy

    unfortunately it's a medical facility.. however, the beam energy should be a constant since you can't modify the beam extraction radius.. there should be away around to figure out this, but as you said, it might not be an easy answer.. it would be easier to just make some experiments and fit...

    Cyclotron exit energy

    So, i'm beggining to work in a cylcotron as operator. Most of the crew here has technical education, albeit not quite a physics degree. When i asked what's the distribution of energies of the particles when they hit the target i got a blank look. How could i determine this? I'm guessing that...

    Undergrad publications

    You got it right on your first guess. Of course, i would read all about it if this goes on.. and i think he may be making us do all the writing stuff.. i suppose we'd be his flying monkeys if we do this :P hmm.. unless someone else comes in and shatter my slowly growing optimism, i'm starting...

    Undergrad publications

    well, it kinda feels like i'm ripping off a project my lab teacher started. He had troubles in his earlier attempts, so when they told him to think about a lab project so we could work on it, he just pulled this thing out. I heard is something not uncommon to just add students in teacher's...

    Undergrad publications

    it's been said on the lab today that maybe the lab work we're doing (i'm an undergrad, 4th year of physics) could be honed into a publication.. my lab partner was really excited about it, but i had my doubts because i don't know what are the future consequences of doing this. i never trust...

    Enthalpy of ideal gas

    oh, thanks! i just need to get the volume out of there, but i could use the other relations to do that. doh! i should've seen that earlier :P

    Enthalpy of ideal gas

    Hello. I'm having troubles solving the enthalpy for an ideal gas. From the equation H=U+PV, i could find H substituting PV=NRT = U/c, but then i need the energy as a function of S and P, so i'd get H as a function of its proper variables (S and P).. I can't find such an expression. It's just...

    Find the potential difference between a and b

    following what you've done, you need one extra equation. If you take the first two and substract them, you get 0 on one side, and a linear combination of i1 i2 and i3 on the other, so with the other equation you have in total two linear equations on three variables (i1, i2, i3), so you have...

    Finding Moment of Inertia of Infinitely Thin Hoop using a Double Integral

    I've found it! i'm gonna post it just ftw. I had some mistakes in my first post, for a start, the integral \int _{0} ^{2 \pi} x^2 \rho dt should be done with ds instead (so the \rho ds would give the mass of that bit, and all makes physical sense). Since ds = R dt we have: I_y =...

    Finding Moment of Inertia of Infinitely Thin Hoop using a Double Integral

    i've found this theorem helpful: http://www.rzg.mpg.de/~rfs/comas/lectures/SportundPhysik/materialien/Aerodynamics/Schulprojekt/Magnus/ajp00181.pdf [Broken]

    Finding Moment of Inertia of Infinitely Thin Hoop using a Double Integral

    I still got some doubts about this.. I've tried many ways to find the moments of inertia I_{x} = I_{y} but i always get some constants wrong. If i parametrize x(t) = R Cos(t) , what's wrong with taking the integral \int _{0} ^{2 \pi} \rho x^{2} dt ? If i do that, i get the correct factor of...

    you can always put it beneath somebody else's air conditioner :D
