TL;DR
This paper presents a theoretical and numerical method to accelerate NMR relaxation using radiation damping, enabling faster return to equilibrium during spin echo sequences.
Contribution
It introduces a novel approach to control NMR relaxation rates via radiation damping, optimizing the process for quicker equilibrium restoration.
Findings
Radiation damping can significantly speed up NMR relaxation.
Optimal damping parameters are estimated and validated through simulations.
The method reduces the time needed for magnetization to reach equilibrium.
Abstract
We demonstrate theoretically and numerically how to control the NMR relaxation rate after application of the standard spin echo technique. Using radiation damping, we return the nuclear magnetization to its equilibrium state during a time interval that is negligible compared to the relaxation time. We obtain an estimate for optimal radiation damping which is consistent with our numerical simulations.
