that's not how statistics work. Well, you're drawing a conclusion for a specific instance based on statistics, which seems similarly foolish. There is evidence for that specific case in question which refutes your statistics-based contention. This is a very silly line of argument to have begun in t...

Would love to know how you read the blacked-out text....

At $.5M, I don't think it's going to be *very* exciting. Sounds more like some kind of feasibility review?

At the risk of derailing the thread further.... Folks that wish to discuss this farther should probably return from whence this board came -- back to nasaspaceflight. That place is full of supporters for privatization, as well as supporters of current policy, as well as supporters of completely dif...

The higher plasma density in WB-8 prompted the need for higher heating power. Higher than what? They don't say higher than expected...they just say higher. True. They also say that they had to replace the electron source as it was insufficient. Now, if it was expected, why would they have built the...

Unless there has been a total re-design of concept, the depth of the well is not controlled by the e-guns per-se, but the static charge on the MaGrid. The e-guns may just need to be larger to MAINTAIN that well. Ah, that sort of makes sense. If you have a denser plasma, that means you need more pla...

Those seem like a good set of options. The wording suggests that the driving force for these changes is that plasma density is higher. I assume that this was unexpected (why build the machine under-specd?). That doesn't immediately make me suspect electron loss (the less precise reading <<we need mo...

During 4Q of 2011, EMC2 has modified the electron injectors to increase the plasma heating. The higher plasma density in WB-8 prompted the need for higher heating power. We plan to operate WB-8 in high beta regime with the modified electron injectors during 1Q of 2012. Seems like if the machine ope...

Re: This Ought to Be Useful for Plasma Diagnostics

http://www.technologyreview.com/computing/39329/?p1=A2 I don't know about the limitations of streak cameras in high-energy environments, but this looks like an interesting diagnostic tool for a whole bunch of things, including plasmas. I believe it works by looking at a single scanline at a time an...

The change to R. Nebel's involvement was before first plasma for WB-8, so I can't see anyway to make a technical deduction one way or another. That's the most important point. If this is really true, and I just can hope so because I don't know you dear quote source, than it is indeed 100% impossibl...

Why throw it overboard?
Roll it up, throw it backwards, unroll it, drag it forward, repeat.
