Next-Gen Polarizers: Optimizing Rb/Xe-129 Spin Exchange Efficiency Beyond 75%
Next-Gen Polarizers: Optimizing Rb/Xe-129 Spin Exchange Efficiency Beyond 75% The transformative potential of hyperpolarized Xe-129 gas in medical imaging and quantum sensing hinges on achieving high nuclear spin polarization, which amplifies MRI signals by up to 100,000 times. Spin-exchange optical pumping (SEOP) with rubidium (Rb) vapor remains the cornerstone for polarizing Xe-129, yet traditional systems…
