i was more interested in emergence of the the diamagnetic phenomenon we are supposing to be the WB.
Sorry, I'm not sure what you're saying you're interested in. My understanding is the electron pressure distorts the field as a consequence of electrons moving along the field lines. Are you looking for modelling of this phenomenon, such as to produce a WB? That would be nice to see. Joel Rogers is trying, but hasn't gotten there yet. He said he would issue a report on his efforts soon.
3. Energy confinement on the WB-7 exceeds the classical predictions (wiffleball based on the electron gyro-radius) by a large factor.

...hang on a sec. shouldn't those classical predictions have given you the correct result? theres nothing non-classical going on, surely?
I think some read this as an endorsement of cusp-plugging. I thought classical just referrred to "non-Wiffleball" cusp confinement (I think someone put it as mirror<cusp<WB).
n*kBolt*Te = B**2/(2*mu0) and B^.25 loss scaling? Or not so much? Hopefully we'll know soon...
Hi Dave - yes, thats precisely what I'm saying. I understand the electron pressure 'analogy' - but it is just that. like Indreks mini-me-polywell artifice. useful, nonetheless. but not fully descriptive.
i would be very interested to see Joel Rogers work. is that Joel Rogers at MIT?
...I thought classical just referrred to "non-Wiffleball" cusp confinement
.. though he specifically says 'exceeds the classical predictions (wiffleball based on the electron gyro-radius)'.
which i took to mean, 'local/micro-model of EXB' on the plasma.
... as I understand it, you are trying to get an order of magnitude estimate of the 'required' diamagnetic effect here. Is that right MSimon? But surely we should have a term for gyro-radius in there somewhere?

No. I was just trying to figure out how many electrons you would need to circulate to "cancel" the magnetic field in the reactor. i.e. the diamagnetic effect. Multiply by 6 to get the total.
The gyroradius question is different.
Engineering is the art of making what you want from what you can get at a profit.
If you will send me your e-mail I will send you the gyroradius (constant field) spread sheet. The actuals will be smaller since the field gets stronger as you get closer to the coil.
thats fabulous. thanks MSimon. I'll pm you my email address.
learned scientists, on the verge of breakthoughs, scrabbling about begging for more MIPS; whats the world comming to. i thought MIPS would be no problem in this day and age.

Yes, I'm not quite sure how to parse that one. At first glance, he seems to be saying it actually exceeds Bussard's WB predictions, but does that really seem likely? I've always assumed it was just awkwardly phrased, misstated (did he mean "cusp" not "wiffleball"?), or specific to something in that thread (maybe he means ion confinement?), but maybe I'm missing something.
Simon,
I think the SETI@home people now use a more general tool that lets you accept spare processor donation time from anyone for any project (at least they were a few years ago) called "BOING" or something. Not sure how helpful it will be, but we might get a couple hundred PCs on it just from T-P.

I think what I have arranged will work out better as Joel will have a fixed configuration and people who can show him how to use it. i.e. initial hand holding.
Maybe later you or I should look up how to set up a SETI@home process and start a thread on it. I have to do some things for the next few hours so if you are ambitious give it a shot. Otherwise I will get to it later.

BOINC.
If you get it set up, I may actually donate some cycles.

Yes. But I'd want the details worked out as part of an @home application.
