Ionisation voltage

  1. Jul 15, 2011 #1
    What voltage would I need to create a mobile ion cloud to pass down a 5mm sq plastic tube a distance of 10mm in air?

    Maybe look at the ionization energy of nitrogen or what ever other molecules you need to ionize . And once its ionized it will move in an E field . You could use a parallel plate capacitor to move the ions. You could use Gauss's law to find the E field in between the plates and then get the voltage from that. Or you could determine this experimentally.
