>How would you make that measurement?
That might be why I’ve never got an answer. U insinuate it’s a difficult and superfluous quantity to measure, and that Lawrenceville haven’t got good measurements for this.
I’d start by measuring the ion energies with particle hit detector, which will give the integral of the electric field over time, then maybe they can measure time duration of plasmoid collapse. Aside any direct measurement, I thought Lawrenceville have a pretty good theoretical plasmoid model now, so they can use that to fill out missing quantities. I’m only interested in a rough estimate ; to an order of magnitude would be great.
