Mr. Simon has it right. Batteries for the coils (high current, low voltage), capacitors for the coil cases (high voltage, low current). WB-6 power input ~ 10 MW.

I don't know Wallace (the CEO) but Seattle is where most of the FRC research has been done recently. I would guess that this is a spinoff company. FRC translation and compression has been studied for a long time.

I hate to disappoint you, but I'm afraid that physicists are a little more boring than terrorists. I don't know if Santa Fe even has a nightlife.... However, Santa Fe does love tourists and I'm sure they would love to entertain you. And if Santa Fe isn't exciting enough, you can always try Juarez.

If you are interested in pumps, the specifications for ITER can be found at: http://www.iter.org/a/index_nav_4.htm . If I am reading this correctly, the pumping power is about 60,000 liters/second. This is ~ 30 times more than the WB-7. It doesn't take a lot of power. Our system takes ~ 500 watts of...

Art: The mirror model is a bit of a handwaving model that I believe Nick Krall came up with. The mirror ratio is calculated from the field where the electron Larmor radius is on the order of the device size. Any smaller field than that will not have adiabatic motion. If particles enter the field nul...

Loss fraction = (summation (pi*rl**2))/(4*pi*R**2) where rl is the electron gyroradius and R is the coil radius. The summation is a summation over each of the point cusps. If you calculate rl from one of the coil faces, then there are "effectively" ~ 10 point cusps (fields are larger in the corners ...

Art et. al.: A few comments on scaling laws…. To a certain extent we are in the same boat as everyone else as far as the previous experiments go since Dr. Bussard’s health was not good when we started this program and he died before we had a chance to discuss the previous work in any detail. Consequ...

The ions also show some magnetic confinement under reactor conditions. Run the numbers. The ion Larmor radii are also smaller than the device size, as are the alpha particles' Larmor radii.

The alphas make about 1000 passes before they exit through the cusps. They leave at essentially full energy.

Art: Here's where I'm coming from. Obviously, I know what's in the data and I know what it is consistent with. We've known that for several months. However, just because a piece of data is consistent with one model doesn't mean that it's inconsistent with another model. When you compare data and the...

Art:

What is A and how does it scale?

Art:

Real theories make quantitative predictions. How come you're scared to do that?

Alex:

3-D Particle-in-cell is extremely expensive. Resolution goes like (N)**.5 where N is the number of particles. You have multiple timescales and multiple spatial scales to resolve. This means supercomputers.

Here's what we know and what we don't know: 1. We don't have the spatial resolution of the density to see if the cusps are quasi-neutral on the WB-7 2. In one-D simulations the plasma edge (which corresponds to the cusp regions) is not quasi-neutral. Therefore, if the cusps are quasi-neutral it must...
