SUMMARY

The discussion focuses on determining the voltage required to create a mobile ion cloud that can travel through a 5mm square plastic tube over a distance of 10mm in air. Key concepts include the ionization energy of nitrogen and the application of Gauss's law to calculate the electric field between parallel plates. The voltage can be derived from the electric field, or the experiment can be conducted to find the necessary voltage empirically. The discussion emphasizes the importance of understanding ionization processes and electric fields in this context.

PREREQUISITES
  • Understanding of ionization energy, particularly of nitrogen.
  • Knowledge of electric fields and Gauss's law.
  • Familiarity with parallel plate capacitors and their operation.

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.
