One of the points I wanted to make is that it looks possible for a well-heeled and determined amateur to at least demonstrate reactions with p-B11, and at the same time, do some valuable investigative work in the lower pressure, higher voltage regime of fusor operation, as well as in detection techniques for charged particles. As far as I know, no one has ever demonstrated a measurable reaction rate with p-B11. It looks like a worthy goal. If anyone does this, I think it will be the fusor community, certainly not the boys with the big toys, with perhaps the exception of the colliding beam folks. The D-T reaction is a much easier shot, but the fast neutron flux with a sizable reactor will pose huge engineering problems.

Gene Meeks of the old Farnsworth team told me that both Miley of UofI and some folks from UofW had either met with or contacted him over the last several years.

Its reaction rate at a quarter million volts falls way short of D-T at only 50kv. It only saving grace that I can see is Direct Conversion possibilities.

>>Check out http://elvis.neep.wisc.edu/~neep602/lecture26.html Figure 28 gives a comparison of reaction rates vs well depth for the popular fusion contenders. The cross-section for p-B11 is particularly interesting, crossing the D-D curve at 50-60 Kev.
