Enhanced alpha channeling with spin-polarized fuel
J. F. Parisi, A. Diallo, J. W. S. Cook
The nuclear spin state of deuterium-tritium (D-T) fuel sets both the D-T fusion cross section and the emission direction of the fusion-born alphas and neutrons. We show two ways th…
Persistence of Deuterium and Tritium Nuclear Spin-Polarization in Presence of High-Frequency Plasma Waves
J. W. S. Cook, H. Ali, J. F. Parisi +2
We present first-principles numerical calculations of the depolarization rate of spin-polarized deuterium and tritium nuclei in realistic tokamak plasmas, driven by resonant intera…
Revisiting Fusion in D-He Plasmas With Spin-Polarized Fuel
J. F. Parisi, A. Diallo, S. Meschini
Spin-polarized fuel (SPF) is recognized for enhancing fusion reactivity, but it could provide other advantages particularly relevant to advanced fusion fuels. In this work, we calc…
Electric Power Enhancement using Spin-Polarized Fuel in Fusion Power Plants
J. F. Parisi, A. Diallo
Using a range of fusion power plant (FPP) concepts, we demonstrate that spin-polarized fuel (SPF) can significantly enhance net electric power output, often by many multiples. Nota…
Tritium-Lean Fusion Power Plants with Asymmetric Deuterium-Tritium Transport and Pumping
J. F. Parisi, S. Meschini, A. Rutkowski +1
Asymmetries in deuterium-tritium (D-T) particle transport and divertor pumping speeds are shown to enhance tritium self-sufficiency in fusion power plants. Using a diffusive partic…
Design of a Thomson scattering diagnostic for the SMART tokamak
M. Kaur, A. Diallo, B. LeBlanc +8
We describe the design of a Thomson scattering (TS) diagnostic to be used on the SMall Aspect Ratio Tokamak (SMART). SMART is a spherical tokamak being commissioned in Spain that a…
Simultaneous Enhancement of Tritium Burn Efficiency and Fusion Power with Low-Tritium Spin-Polarized Fuel
J. F. Parisi, A. Diallo, J. A. Schwartz
This study demonstrates that using spin-polarized deuterium-tritium (D-T) fuel with more deuterium than tritium can increase tritium burn efficiency (TBE) by at least an order of m…
Doubling Fusion Power with Volumetric Optimization in Magnetic Confinement Fusion Devices
J. F. Parisi, J. W. Berkery, A. Sladkomedova +17
A technique, volumetric power optimization, is presented for enhancing the power output of magnetic confinement fusion devices. Applied to a tokamak, this approach involves shiftin…
Kinetic-Ballooning-Bifurcation in Tokamak Pedestals Across Shaping and Aspect-Ratio
J. F. Parisi, A. O. Nelson, R. Gaur +16
We use a new gyrokinetic threshold model to predict a bifurcation in tokamak pedestal width-height scalings that depends strongly on plasma shaping and aspect-ratio. The bifurcatio…
