Double slit experiment for AP physics

    Hello,

    I'm not sure if this is the right part of the forum to be posting this in (if it's not, feel free to move me), but I have a question about the double slit experiment.

    For my AP Physics class, a group of seven other guys and myself are researching the double slit experiment, both with light and with electrons. Does anyone here have any advice on how a group of high schoolers would go about performing the experiment with electrons? (The light portion is easy, and our teacher is actually giving us access to a fairly large laser he has for another class).

    I'm currently doing one of these for a science fair, and during my research, I heard something about doing this with a single photon laser. I didn't know these existed (and I have yet to find one.) But if you can learn more about these, it might be interesting to look into.

    It basically fired single photons overnight onto a film, then let the film develop, showing the interference pattern.

    Not sure if you cared much about that, but anyways...
    I also read something about cracking open a TV to get an electron "gun."

    Theres also a Electron accellerator tutorial on instructables, maybe you can modify that for your needs.
