==Presentation edits==
 
*Recreate ion production rate (IPR) vs beam energy (T_e) graph for large beam energies, include units for IPR.
 
*Switch scattering angle definition (small vs. large for the v_e&v_g comparisons)
 
*Change v_i to v_g in 3rd case (should be v_e>>v_g, not v_e>>v_i)
 
<math alt="Square root of pi">\sqrt{\pi}</math>
 
==Ideas for the future==
 
*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 v_g 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)
