Over the last two decades there have been many advances in the field of hyperpolarized (HP) noble gas production and imaging, largely enabled by the development of low-cost, high-power frequency-narrowed laser diode arrays (LDAs) and the improvement of 129Xe polarizer technology in general. Here we present the development and features of the new 3rd-generation Batch-Mode 129Xe hyperpolarizer. As with most previous 129Xe polarizers, the new device utilizes Spin Exchange Optical Pumping (SEOP), a process in which resonant, circularly polarized photons optically pump Rb electrons, which in turn hyperpolarize the 129Xe nuclear spins via hyperfine interactions (the “spin-exchange” process).
