My guess is they got exactly what they expected: a good wiffle-ball tested with helium, and later neutron counts from deuterium comparable to WB-6. I remember Tom saying it looked they'd done a lot to ensure good counts, so I'd be surprised if they never ran d-d.
I would imagine they are now either doing or preparing for peer review.
As for "nuanced" I think some people may be reading a bit too much into that.
Nebel said it's way too early to talk about the answers to those questions. For one thing, it's up to the project's funders to assess the data. Toward that end, an independent panel of experts will be coming to Santa Fe this summer to review the WB-7 experiment, Nebel said.
"We're going to show them the whole thing, warts and all," he said.
Because of the complexity, it will take some interpretation to determine exactly how the experiment is turning out. "The answers are going to be kind of nuanced," Nebel said.
Do you guys remember when Art Carlson first showed up here? He immediately raised several complex points that made perfect sense from a LTE plasma physics background, we tried our feeble best to address them, then Nebel would show up and place things in an entirely new context (I don't think I ever understood one of his answers without first looking up several terms and concepts) which explained how Polywell could get around the problem -- with appropriate caveats where problems exist or answers are unclear.
When they talk about the answers for the experts being nuanced, I'm guessing that just means there will similarly complex discussions in the peer review, esp. regarding the uncertainty of how the results would scale to a larger machine.
Hopefully, the discussions beyond that center on whether we should shoot for a WB-100 or do more validation on a smaller machine and how either would be paid for, rather than whether to stop funding this line of research.
