Low-voltage power from a p-B11 fusion alpha storage ring?

Here's another dumb question from a non particle/plasma physicist.

Imagine a truncated-cube Polywell with sufficient B-field intensity that the p-B11 fusion product alphas exit mostly along the magrid coil axes. Further imagine curved, magnetic and/or electrostatic beam guiding tubes (design details ignored here) that channel the alphas into a toroidal alpha-storage ring surrounding the magrid (design details again ignored). For a first pass, let's assume the guide tubes have flared ends at the alpha inlets, as the alpha "beams" will want to expand after they pass the magrid coils. Four of the curved guide tubes would have the same arc length. The remaining two, originating from the magrid top and bottom coils, would be longer. The guide tubes are assumed to intersect the storage ring tangentially at six equally-spaced points. The travel time through the two longer guides would be greater, which hopefully doesn't matter after steady-state operation is reached.

Question --
Could the alphas circulating in the storage ring be used to produce low-voltage electrical power with a reasonable efficiency?

In theory there is no difference between theory and practice, but in practice there is.

To error is human... and I'm very human.
