Abstract

In the view of growing application of hyperpolarized xenon in various fields of science and medicine, the avail-ability of relatively low cost, reliable polarizers is of the utmost importance. The article describes the design andconstruction of the spin exchange optical pumping (SEOP) polarizer for129Xe, operating in the stop-flow mode.Using 9 W of laser power at the input of 1 litre optical pumping cell, a single batch of the gas mixture is polarizedin about 15 minutes. The xenon nuclear polarization is calibrated against the thermally polarized water and xenonphantoms. It reaches about 40 % in the gas mixture containing 3 % of isotopically enriched xenon. The hyper-polarized xenon is accumulated in the detachable liquid nitrogen dewar containing 0.6 T Halbach magnet withthe cold trap inside. All components that are important for the effective operation of the system are describedin detail, and possible improvements are pointed out
