 This is a significant point of confusion for scientists more familiar with more 'conventional' fusion plasma physics.Note that for the electron beta, only the electron number density and temperature are used, as both of these, but especially the latter, can vary significantly from the ion parameters at the same location.formula_1

Most experiments on polywells involve low-beta plasma regimes (where "β" < 1), where the plasma pressure is weak compared to the magnetic pressure.
