Electrostatic plasma confinement

[Mattenerinfo]

Hello,
Working on a little project, just some electrostatic plasma confinement, and the high energy plasma is being expelled out a nozzle, and a colleague of mine proposed that we use an electron beam through the center of the nozzle, the nozzle already having a bit running down the center that we can easily have a cylinder hollowed for this, but I would like to know if any of you would know an equation that would give us the predicted added force that the ions would then have ejected from the nozzle, as I can't seem to find any past projects like this. I considered using a standard modeling system but it is to much oriented at interaction with none moving or opposing forces. I guess what I am asking is, does anyone happen to know the equation to factor in this added force of the electron beam leading the ions?

I'm not sure what type of equation you are looking for, but the basic equation to calculate the force of a particle in an electrostatic field is F = qE, where q is the charge of the particle and E is the electric field. You can use this equation to calculate the force of the ions in the electron beam.
