Absolutely! Super conducting coils..... just as in the tokamakish ITER. The dollar limit is the sky, of course, if one wishes to pull out all the stops with a barrel full o' dough.
Thus far, they haven't proven much of anything regarding the polywell and they will be lucky to have the old fashioned, current hog, hot coils they do have survive or function well enough or long enough to even advance out of the theoretical, "I got this idea stage".
All this is, supposedly, almost ready to test, again, I hear.
More wait-and- go-seek.

Progress may have been a good thing once, but it just went on too long. - Yogi Berra
Fusion is the energy of the future....and it always will be
The more complex the idea put forward by the poor amateur, the more likely it will never see embodiment

Re: Polywell - Magnetic Electron Confinement or Magnetic Grid Shielding?
Over at talk.polywell I have been working on these heating issues.
In the center of the magnet structure will be superconducting coils with LHe cooling. Next a vacuum space. Next LN coolant. Next a vacuum space. So far standard MRI stuff.
Next H2O at 300K (again other than the H2O - similar to MRI). Then another vacuum space. Then H2O at around 600K or so to absorb the heating from alphas and other impingement.
Cooling this rig is not the biggest problem. Getting it to work at all (net energy production) is.
So far Drs. Nebel and Park are confident they can get it to work. As was Dr. Bussard. They may be right.
In any case it will only take a few years and a few bn to prove them right or wrong if the current experiments green light further efforts. About 20% of the money and 10% of the time ITER is supposed to take.
See what Dr. Nebel has to say in the comments here:

Going through the exercise may suggest better approaches. In any case like ITER it will be good science.
