| ABSTRACT: |
Searches for new sources of T violation beyond the Standard Model in the first generation of quarks appear to be needed to explain the baryon asymmetry of the universe. The T violation experiment under development at KEK using polarized neutron transmission through polarized targets such as 139La and 131Xe which have large parity violation at neutron resonances, needs (1) large polarized targets, (2) ways to monitor the neutron polarization in the target to avoid false effects. I will describe recent advances in the production of polarized 129Xe for medical imaging using spin-exchange optical pumping and ideas to use scintillation light from polarized neutron captures in the polarized xenon target which may help the experiment. The medical imaging goal of 40% 129Xe polarization at rate of 120 bar-liter/second could also be interesting for experiments in other areas of nuclear/particle physics. |
