WB-8 Testing Pre-solitication
That's quite interesting. One thing I wonder about.
The size of the vacuum chamber does imply the same sized coils ...
Is that full casings or half casings? That is, 26/6 = 4.5 machines. It seems unlikely that they would order extra just to have lots of spares, though. Still, I wonder if this data implies that WB8 will use WB-7 sized coils? That is, use coil casings that are already on hand.On page 6 - 26 coil casings for WB-7. Should be good for 2 machines plus a spare. Ordered? Sept 2007.

They bought a defibrillator:

Handy for electrical shock. Be sure to kill all power before attending to victim.

And yeah. I think WB-8 will be a LN2 cooled (evaporation) WB-7 size machine in order to get higher pulse power in the magnets.
WB-9 just about requires SC magnets for the next step up in size.

Now this is interesting.
After thought. Its a CPFF contract so "Afford" isn't the issue. Justification is the issue and that depends on what they plan to build, size wise. What are some of the research pro's and con's of staying with the same WB-7 machine dimensions?
One Pro - Can verify the B^4 power scaling independently of R^3.
In that price range maybe they can afford a new, bigger chamber for new machines.Vacuum Chamber, WB-7; incl. cutting,
machining, polishing, welding, port install & 2
doors $31,000.00

DrN has implied larger. There are enough casings for 13 magnets. The Statement of Work said small scale circular magnets on main face cusp axis. It did NOT say cube. There are magnets enough for a dodec plus a spare. A dodec with the same size magnets has a bigger core. It fits. Hmmm.MSimon wrote:On page 6 - 26 coil casings for WB-7.

If they were modifying the second set for cooling while using the first set in WB-7 it is more than possible WB-8 will be up and running in short order.
Phoo. Just because they bought them doesn't mean they HAVE to use them. But still...
Maybe the WB8 will be a cooled trunc-cube and WB8.1 will be a cooled trunc-dodec. You know, use the first twelve casings in WB7.1 while they build and check out WB8 with the next twelve. Then test WB8 while they rebuild WB7.1 into the rest of the coils for a WB8.1 dodec. Well, I can dream.

On a slightly different note did anyone notice a classification statement for the technical data?
If a different geometry is going to be used I would expect it to be done in WB-9. For scaling you want apples to apples. First you figure out how the machine works. Then you apply that knowledge to make the machine work better.KitemanSA wrote:DrN has implied larger. There are enough casings for 13 magnets.

The data is company proprietary. The Navy gets to use it for its own purposes.

Which is why I suggested the WB8 would be a trunc-cube, and only when they want to try for pB&j do they improve things to a dodec.MSimon wrote: If a different geometry is going to be used I would expect it to be done in WB-9.

Phoo. All speculation. Meaningless, but fun.
The "follow-on" to WB-8 is the 100MW machine, not WB-8 itself. It looks like WB-8 will produce, appropriately enough, something around 8 watts.Betruger wrote:100MW is tantamount to an at least break-even design, isn't it? WB-9 is explicitely designated as "fusion demonstrator". How could WB-8 be 100MW if WB-9 is the fusion demonstrator?
