				Polywell design worksheet

				In the past I have built excel spreadsheet design worksheets to help determine design parameters and get a napkin sheet preliminary design without having work through all the numbers every time I wanted to change something.  Sort of an A changes B which causes C sort of deal.  I would like to start a Polywell sheet, but I'm not sure what numbers are important and drive the model and which are not.  for instance do I start with an assumed well diameter or is magnetic field strength drive.  Is magnet size a driver or driven.  Is the spacing for the grid a constant or does it depend on field size.  I'm going to start the sheet with what I think are drivers, but input will be appreciated.

I have already done such a sheet. Why not do yours and we can cross check?
Start with radius. Well voltage. Drive energy (center of mass). Reaction rates. Energy density. Magnetic field. Wiffle ball factor.  etc.
