As I understand it, the physics are so fast the "pulse" as it sweeps through beta is long enough to tell us what we need to know to get to a reactor (and whether that is possible).
The "pulse" or "sweep" gives us a good idea of whats going on in the 30cm WB-6&7 size. And no doubt, real good reason to keep building WB's.
Scale it up, doesnt the sweep take a lot longer in a larger vessel? Such that the 4 or so milli seconds involved in running WB-7, wont do in a larger machine. The "sweep", on larger WB's will be much longer. And dont we expect a very different plasma in a 3 meter Polywell, than in a 30cm Polywell?
I like the p-B11 resonance peak at 50 KV acceleration. In2 years we'll know.
