John,
I didn't, but should have, realized from our other talk that was your setup, not something else (head slap, doh). May I suggest moving further talk of the detector part of this to metrology, and the details of your setup (should you find time to document them and a willingness to share) be moved to "other forms of fusion" with a back-link to this so I don't have to move this to make it coherent? (this is hard to do in this software so far on my learning curve, and risks us losing good content so I'm loath to do it if I don't have to). Once we continue in those places, we can edit a post here to link there.
I too am very interested in the sorts of things measured here -- we are having non isotropic outputs too and trying to study that, so let's put further talk about detectors into the measure place, and what you are measuring into the place for that (other forms of fusion maybe?). I have myself done some linear pinch experiments at 100's of kA that got down to a micron (maybe a little less) for X ray source sizes. If that were making neutrons instead of X rays (we used tungsten plasmas for our work then) yes -- it would be interesting indeed to see the pattern of output, especially vs time on a pretty fast scaling like the DPF guys are working with -- it matters about "when" things happen to really understand the process - in order to improve it.
I've not yet had time to put the details of that experiment up here, but I do plan to -- it worked really well and wasn't really hard to do. One could easily make it happen in D instead of W I think, but haven't yet. Inertia -- I have 18kj worth of maxwell caps just sitting. (120 uf x 10kv x 3 of them -- 18nh ea series L and vanishing R, rated for 100ka each shots at long life). But my other work is also going so well I don't want to go for that way just now myself -- but have also been getting ready to -- just in case. I am listening and want to be informed.
Posting as just me, not as the forum owner. Everything I say is "in my opinion" and YMMV -- which should go for everyone without saying.
