I Double slit experiment with electrons

  1. Dec 12, 2016 #1
    When it's desired to detect an electron coming through one of the slits in the mask of the double slit experiment, how exactly is the detection done without blocking the electron from reaching the background screen? In another thread it's mentioned that a semiconductor detector is placed behind one of the slits, but that would presumably intercept the electron and prevent it from reaching the screen.

    A passing electron generates a magnetic field pulse. That might be detectable with a Hall efffect sensor.

    Thanks DrChinese and BvU for the references and the suggested electron detection method. I'm currently reading the paper DrChinese provided a reference for.
