Polarized fusion, its Implications and plans for Direct Measurements in a Tokamak

A. M. Sandorfi,
A. Deur,
C. Hanretty
et al.

Abstract: Our energy-hungry world is burning. A long-term solution, possibly the only ultimate one, that is just approaching the horizon after decades of struggle, is fusion. Recent developments allow us to apply techniques from spin physics to advance the viability of this critical option. The cross section for the primary fusion fuel in a tokamak reactor, D+T → α+n, would be increased by a factor of 1.5 if the fuels were spin polarized parallel to the local field. Simulations predict further non-linear power gains in … Show more

“…There are multiple issues associated with delivery of the pellet fuel. The actual preparation and delivery of spinpolarized pellets has many challenges that are discussed in detail elsewhere [5]. To summarize, we envision filling gasdischarge-polymer shells like those used in inertial fusion research [33] with polarized fuel.…”

“…Equation (5) states that the CFP countrate C is C(E 3 ) = ˝dl dA dΩ S(r, v 3 ), where dl is over the sightline trajectory, dA is over the detector area, dΩ is over the solid angle accepted by the detector collimating structure, and S(r, v 3 ) represents the D- 3 He emissivity (in reactions/volume-time) of CFPs that are emitted at position r along the sightline with the correct values of detected energy E 3 and solid angle Ω. This appendix sketches the methods used in the calculations of sections 2.1 and 4.…”
