More results from axial field coil
(0) CommentsWe have returned to testing the axial field coil, which we think can control the angular momentum and thus the size of the plasmoid.
(From LPP’s September Report.)
So far we have fired only a limited number of shots with the coil this month (15 in all), but it is interesting and encouraging that this series has yielded the two highest-yielding shots of the whole month.
In both shots, on Sept. 1, the coil was producing a field twice that of the earth’s magnetic field. In the best shot, 9-01-10-14, we observed 0.7 x 10^11 neutrons, twice as much as any shot fired this month without the coil. Since we did not see this same effect with the field at 3 times that of the earth, it appears to be a fairly narrow optimal range. In addition, we are not yet seeing as high yield as we expect to at this current, close to 1 MA. That would be nearly 10 times higher than that observed. However, we think we may understand why this is occurring and what to do about it—see next section.
