To get back on topic: I found this abstract for a 2005 article describing the FRC and beam stuff that UC Irvine was doing with Tri-Alpha before everything went quiet. I don't know if this is the most recent document available, but I hadn't seen this before. Does anyone have acces to that journal? Ed...

I've got a student license for OOPIC-Pro, it was only $50 but it was only good for a year though. It's not exactly the best tool for what we're trying to study. It doesn't allow the plasma to modify a background magnetic field if you chose to add one, so we can't find anything about diamagnetic effe...

@rcain:by the text of the link, I'm guess 2008. :lol: Those are the parts I homed in on too. The fact that they've got a detailed, well-supported plan is very hopeful. As I recall, the theta-pinch folks were having a hard time getting enough flux to allow neutral beam capture. BTW, it really bugs me...

HyperV - plasma liner
HEre's an interesting magnetized target concept, which I think stands a better chance than General Fusion: HyperV Technology http://www.hyperv.com/ has the idea to shoot jets of high-velocity, low-temp plasma to compress a compact toroid target. It's basically a form of plasma liner magnetized targe...

FRC: ways forward
It looks to me like the two main approaches to FRC fusion are 1) pulsed a. theta-pinch b. imploding liner c. translation d. gun-formed/merging e. inductively sustained 2) sustained a. rotating magnetic field b. neutral beam It looks like U. of Wash folks are pushing two programs at once: the transla...

jmc: ok, here's my take on the tapered flux conserver: It won't pull any new magnetic field lines into itself, so the field/flux already needs to be there, so it doesn't do you any good unless the conserver contracts as in MTF. Well, it may help somewhat in that it keeps the displaced flux of the FR...

Personally, I've always been amazed and grateful that Dr. Nebel has been willing and able to comment as much as he has. I'm sure the silence is a result of sheer busyness right now: you'd be busy too if you won an $8mn contract! That doesn't mean I can't hope for more tidbits sometime though! I'm st...

Good find on that paper! That's a really bright idea: I'm jealous! Slough's making a sort of transmission line out of the coils by adding parallel capacitance, so that the waste energy from each coil goes into the next. The kids over at the coil-gun forum could learn from that. Changing the inductan...

Hmm? So actually have both coils turned on in opposite directions and then just stop one of them, instead of trying to start one? That's an idea. So maybe you could have a giant SC solenoid, and pulse these reversal coils to create a traveling mirror region. Then the back side of the mirror region i...

So you're saying, used the pulsed magnets to accelerate the FRC like a coilgun, then slam it into a tapered flux conserver and let that force the compression. Hmm. How fast is 50 keV for hydrogen? It might be hard to synchronize the accelerating coils to get something going that fast, that's probabl...
