Homework Help: MATLAB: Ion Trap

  1. Jan 13, 2010 #1
    Hey guys, I asked this before but I don't know where the thread is, and now it's more detailed, haha.

    So attached is a png of the trap design. I'm trying to make a function on MATLAB where I can predict the ion's movement/oscillation. So the E1-E5 are electrodes, which have a combined potential of Vs, and Z1 has a potential of Vz. So I figure I'm going to do a function which fits ode45, if you don't know what that is, you can still help probably.

    But anyways, those electrodes have a potential set upon them. Can someone explain to me what exactly that means? Like, say Vs = 1kV and Vz = 10kV... If I were near the middle of the field free region, would I be feeling the same potential as opposed to if I were right next to them? What exactly does, "these electrodes have a potential of ___ on them" mean?
