Recreate ion production rate (IPR) vs beam energy (Te) graph for large beam energies, include units for IPR.
Switch scattering angle definition (small vs. large for the ve&vg comparisons)
Change vi to vg in 3rd case (should be ve>>vg, not ve>>vi)

Thinking about distance dependence on IPR -- perhaps convert rates to ions/(m*s) instead of ions/(m^3*s)
Try renormalizing IPR to beam current (i.e. express rates as ions/(m^3*s*A))
Thinking about how ideal the residual gas really is -- we're assuming currently that the residual gas is ideal
Calculate residual gas speed vg for each gas
Research Mott scattering -- relates to polarization
Consider what happens to the electron leaving the ion (i.e. the electron that is knocked out of the residual gas molecule) -- does it leave the beam? How much energy is transferred to the ion by the electron? Does it depend on temperature, potential energy, etc.?
Research repelling anodes as a 4th option for ion clearing
Start researching ion trapping/neutralization - starting with beam gaps (as used in e+/e- beams)
