A compact self-sustained 129Xe polarizer was set up which can be easily transported and put into operation. The concept of a partially heated spin exchange optical pumping cell was used in this setup. In the beginning of operation high 129Xe polarizations were measured with an online NMR setup. A steady decrease in light transmission through the pumping cell was seen. Although utilizing higher laser power after changes in the setup a significant decrease in the deduced 129Xe polarization was seen. The effects are discussed and changes to circumvent these effects are pointed out.
